It has been a summer of change for Real Madrid, who have seen manager Zinedine Zidane and record goalscorer Cristiano Ronaldo both depart since their Champions League triumph against Liverpool in May.
New boss Julen Lopetegui takes charge of his first competitive match tonight in a Madrid derby against an Atletico side that lifted the Europa League title last season.
Make sure you don't miss a moment of the action courtesy of our minute-by-minute updates below.
REAL MADRID: Navas; Carvajal, Varane, Ramos, Marcelo; Kroos, Casemiro, Isco; Bale, Benzema, Asensio
ATLETICO MADRID: Oblak; Juanfran, Savic, Godin, Hernandez; Saul, Koke, Rodrigo, Lemar; Costa, Griezmann
Thank you very much for joining us for tonight's match as Atletico Madrid beat city rivals Real in extra time to win the 2018 UEFA Super Cup in Tallinn. I will leave you with our match report, and be sure to check back in at the weekend when the Spanish domestic season gets underway!
From me, though, it is goodbye for now!
Atletico Madrid draw first blood in the 2018-19 season, then, as they come from behind to beat Real Madrid 4-2 in the UEFA Super Cup final, winning the trophy for a third time in their history.
Two goals from Diego Costa either side of strikes from Benzema and Ramos sent the game into extra time, but Atletico pulled away in the opening 15 minutes of the additional period with Saul Niguez and Koke getting the goals which ultimately earned Atletico the trophy.
It is not a good start to life at Madrid for Lopetegui, and there are questions to be answered regarding how they will cope without Ronaldo now.
120+1 min ET ATLETICO MADRID WIN THE 2018 UEFA SUPER CUP!
120+1 min ET REAL MADRID 2-4 ATLETICO MADRID
120 min ET There will be one minute of added time at the end of this match.
118 min ET Atletico's players thrive in this scenario. They are pulling out all the time-wasting tactics as the clock continues to tick down.
116 min ET Real are looking increasingly resigned to losing this game now. They are still trying to push forward for a goal back, but time is running out and Atletico are holding firm.
114 min ET Modric tries to drag Madrid back into this match with an effort from outside the box which goes through a crowd of players. Oblak reacts well, though, to get down and make the save.
112 min ET Surprisingly it has taken 112 minutes for Ramos to go into the book, but he does so here for a bodycheck on Niguez.
111 min ET Atletico break forward again and Vitolo takes the ball into the area, showing great footwork to get away from a couple of defenders with very little room to work with. He beats Carvajal about three times in quick succession, but is eventually crowded out.
109 min ET ATLETICO MADRID SUB: Costa has had a really good game tonight, but he was walking a tightrope having already been booked. He is replaced by Jose Gimenez.
108 min ET How about this fact fans - Real Madrid never once conceded four goals while Zinedine Zidane was in charge...
106 min ET We back underway once again for the second half of extra time. Is there any way back for Real Madrid?
Well, that first period of extra time could have hardly gone better for Atletico!
Simeone's side now lead 4-2 over Real Madrid courtesy of goals from Saul and Koke, both of which were of real quality. Real have just 15 minutes remaining to get back into this game now!
105+4 min ET REAL MADRID 2-4 ATLETICO MADRID
105+3 min ET Vitolo picks up a booking for preventing a free kick from being taken.
105+1 min ET There will be two minutes of added time at the end of this first half of extra time.
104 min ET Surely that is game over now! It is a sweeping move for Atletico, and it is expertly finished of by Koke!
Costa turns the ball back to Vitolo, who in turn sweeps it into the path of an unmarked Koke. The midfielder still has work to do to finish it, but his first-time effort leaves Navas no chance and it nestles into the bottom corner.
104 min ET REAL MADRID 2-4 ATLETICO MADRID (KOKE)
103 min ET Enough talking, only seeing this goal yourselves can do it justice. Feast your eyes on this stunner...
102 min ET REAL MADRID SUB: Here is Real's final change of the night as Borja Mayoral replaces Kroos.
101 min ET Modric is the latest player in the book for a swinging arm when going up for an aerial ball.
100 min ET That is a goal worthy of winning any game. I was expecting quite a tight match with the start of the La Liga season so close, but this is turning into a thriller.
98 min ET What a strike from Saul to give Atletico the lead once again!
The chance initially looks like it might have gone when Costa's pass to Partey is a little overhit, but the winger manages to send it back into the middle for an unmarked Saul. The midfielder still has plenty to do, though, and he catches his volley brilliantly to leave Navas with no chance.
98 min ET REAL MADRID 2-3 ATLETICO MADRID (SAUL NIGUEZ)
97 min ET It is Real Madrid who have made the brighter start to extra time here. They are looking fresher than Atletico at the moment.
95 min ET Atletico are only able to clear the ball as far as Carvajal, who fires a dipping volley towards goal, but it is nice and central for Oblak, who gathers it with minimum fuss.
93 min ET Both sides have made three changes already tonight, but they are permitted a fourth in extra time now. It will be interesting to see whether they use it to freshen up legs or with one eye on a penalty shootout.
91 min ET Real Madrid get us back underway for the first period of extra time!
Extra time it is in Estonia, then! Ninety minutes could not separate the two Madrid clubs in this Super Cup clash, so we will have another 30 just a few days before the start of the season!
Diego Costa got both goals for Atletico, while Benzema and Ramos are on the scoresheet for Real.
90+4 min REAL MADRID 2-2 ATLETICO MADRID
90+3 min Almost a dramatic late winner with the last kick of normal time as Bale clips a cross into the middle. Marcelo finds himself as the furthest forward and tries an acrobatic scissor kick, but he gets it all wrong and the chance goes begging.
90+2 min There will be a minimum of three minutes added time at the end of his match. Can either side find a winner?
90+1 min Cabellos goes into the book for a late challenge on Correa.
90+1 min ATLETICO MADRID SUB: Another change for Atletico sees debutant Lemar replaced by Thomas Partey.
89 min Almost a chance for Atletico to grab a late winner through Costa, but he just can't get a shot away after being teed up by Correa.
87 min The pace of the match has really slowed in the last few minutes, which is perhaps a sign that both teams are saving themselves for extra time. Not ideal just four days before the start of the new league season!
85 min Just five minutes remaining of normal time now! Neither set of players or managers will particularly want extra time, but that is where we are heading as things stand!
83 min REAL MADRID SUB: Another change for real Madrid as Lucas Vazquez replaces Isco. Remember, should this one go to extra time then both sides will be able to make a fourth substitution.
81 min We are set for extra time and perhaps penalties as things stand, then! Can either side get a winner to prevent that?
79 min Atletico have the equaliser with just over 10 minutes remaining, and it is a second for Diego Costa!
It is really poor from Marcelo as he keeps the ball in play but only succeeds in playing Juanfran in down the right. Juanfran in turn squeezes a pass inside for Correa, who reaches the byline inside the area before cutting in back into the six-yard box, where Costa is waiting to fire into the roof of the net from close range!
79 min REAL MADRID 2-2 ATLETICO MADRID (DIEGO COSTA)
78 min Costa tries to make something of a ball into the box by taking it down and sending an acrobatic cross into the middle, but there is a lack of support there.
76 min REAL MADRID SUB: Concern for Casemiro here as he limps off to be replaced by Dani Ceballos. It looks like the Brazilian could be a doubt for the league opener this weekend.
74 min Just over 15 minutes remaining in this match now and Atletico really need to step things up a gear. They have not really threatened Navas's goal at all since scoring in the very first minute.
72 min ATLETICO MADRID SUB: A second change for Atletico as Vitolo replaces Rodri.
71 min Crucial block from Niguez as he gets himself in the right place to prevent Varane's goalbound effort from testing the keeper. The ball bounces back out to Modric, who works space to shoot but them curls an effort off target.
70 min An Atletico free kick from the centre of the pitch comes to nothing but they recycle the ball and Hernandez has the chance to put it into the box again. However, he gets it all wrong and puts it straight behind for a goal kick.
68 min Real look in complete control of this match now. Atletico suddenly need to push forward more and take a few more attacking risks with just over 20 minutes remaining.
66 min Real are pushing for a third now and Benzema manages to get a shot away from an angle, but it lacks the power to really trouble Oblak.
65 min Costa picked up a booking for his protests after that penalty, and he is involved with Ramos again here. He gets tangled up while running for the ball and ends up trampling on the Madrid captain's neck. It looks to be accidental, though, and the referee seemingly agrees.
63 min Is there a better defender in front of goal? Sergio Ramos puts his side ahead with a penalty oozing with confidence - who needs Cristiano?!
Ramos strolls up to the spot kick, watches the keeper all the way and then sends him the wrong way, tucking his effort into the bottom corner. Real lead!
63 min REAL MADRID 2-1 ATLETICO MADRID (SERGIO RAMOS, PEN)
62 min Penalty to Real Madrid! A cross comes into the box from a corner and Juanfran gets himself in a muddle when marking Benzema. His hand is up and the ball hits it, so it is the right decision!
60 min Correa is the first Atletico player in the book tonight for a foul on Casemiro.
60 min Bale collects the ball in a good area just outside the area and he tries to beat Godin with some good skill, but the Uruguayan is not fooled by such tricks and makes a good well-timed challenge.
58 min ATLETICO MADRID SUB: Atletico also make a change of their own during the stoppage, with Angel Correa replacing Griezmann.
57 min REAL MADRID SUB: Here is the change, with Modric replacing Asensio.
56 min We are about to see Luka Modric for the first time since the World Cup final. Could it even be one of the last times we see him in a Real Madrid shirt?
54 min Marcelo becomes the second Real Madrid player in the book tonight for a challenge from behind on Juanfran.
52 min Good spell of possession for Atletico as they look to take the game to Real, but Lopetegui's side are well drilled and refuse to get dragged out of position. It is almost like roles reversed at the moment.
50 min Atletico will want to see more from Griezmann in this second half. The World Cup winner has barely been mentioned so far tonight, but Atletico could need a moment of magic from him.
48 min A reminder that we will have extra time and penalties if nothing can separate these two teams inside the 90 minutes - something I'm sure both would want to avoid with the start of the La Liga season just around the corner.
46 min Real Madrid get us back underway for the second half in Estonia!
The first half comes to an end in this UEFA Super Cup clash and we are all square between Real Madrid and Atletico Madrid.
It has been an entertaining affair so far, with Real dominating possession as expected by Atletico proving as tough to break down as ever. A very interesting 45 minutes awaits!
45+1 min REAL MADRID 1-1 ATLETICO MADRID
45 min There will be one minute of added time at the end of this first half.
43 min Real have seen the lion's share of possession in this first half, but Atletico are used to that - particularly against this calibre of opposition. Simeone's side have halted Real's momentum now and it is an even game again at the moment.
41 min Look away Liverpool fans - a Loris Karius shirt has been spotted in the Real Madrid end for tonight's game...
39 min Bale tries his luck from range after cutting inside from the right, but it needs to be a stunner to beat Oblak from there and the Atletico keeper makes a comfortable save.
37 min Less than 10 minutes remaining of the first half now and we're still all square in this Madrid derby. It has been an entertaining affair so far, without a huge amount of clear chances.
35 min Asensio becomes the first name in the book tonight.
33 min Atletico need to do something to change the course of this match as Real are very much on top at the moment.
31 min Here is that Benzema equaliser, with a starring cameo from Bale...
29 min Real are looking dangerous now! Asensio almost makes it two goals in as many minutes as he races down the left flank before cutting inside and bending an effort inches past the far post.
I'm not sure whether Oblak would have reached that if it was on target!
27 min Real Madrid are back on level terms, and Karim Benzema is off the mark for the new season!
This goal is all about Bale, though; the winger bursts past one defender with pure pace down the right flank and then swing a beauty of a cross into the middle with his weaker foot. Oblak cannot come for it while the defender's can't intercept it, leaving Benzema there to just nod it home from close range.
27 min REAL MADRID 1-1 ATLETICO MADRID (KARIM BENZEMA)
25 min Marcelo tries his luck from range, and you wouldn't back against him considering his goalscoring record in the Champions League last season. However, this one is on his weaker foot and it is always rising over the crossbar.
24 min Atletico haven't shown too much going forward since their first-minute goal, but a 1-0 win suits them just fine. There aren't many teams in world football harder to come from behind against.
22 min Simeone's side are pressing really well high up the pitch. Varane has just been caught in possession by Costa inside his own half, although nothing comes of it on this occasion.
20 min Atletico are making life difficult for Real Madrid here, although that will not exactly be a newsflash for the Champions League winners. Simeone's side are as hard to break down as ever, with Madrid struggling to create much at the moment.
18 min Superb stop from Oblak to keep his side in front! Marcelo advances down the left flank and sends a low cross into the middle which Asensio flicks cleverly towards goal. However, Oblak is sharp and gets down well to push the ball away.
16 min Atletico now win a free kick and have the chance to put the ball into the box, but Lemar overhits it and Griezmann cannot reach it before it goes behind for a goal kick.
14 min Kroos delivers it into a dangerous area, but Niguez is well placed to head it away in a packed box.
13 min Lovely skill from Bale as he skips inside past two defenders, drawing a free kick in a dangerous crossing position...
12 min Real Madrid have begun to settle into this game now and are seeing a lot more of the ball now. Atletico are looking firm as ever at the moment, though.
10 min Better from Real as they come sweeping forward with a couple of slick passes, but it comes to a halt when Savic makes a perfectly-timed sliding challenge on Bale. That was an important interception, and he got it spot on.
8 min Ramos catches Costa in the face with an elbow and is perhaps a little lucky to get away with only a talking-to. That is going to be one hell of a battle tonight.
7 min Here is that stunning Costa strike for your viewing pleasure...
5 min The Atletico fans are making plenty of noise now, and so they should be. Their side have made a brilliant start to this match, with Real very slow to get going by contrast.
3 min Not an ideal start to the post-Cristiano and post-Zidane era, then!
1 min Oh my word, what a start this is for Atletico Madrid! Diego Costa gives his side the lead after only 52 seconds!
It is brilliant play from the former Chelsea man too; he flicks the ball on to himself and shrugs off a challenge from Ramos, who should have done a lot better. Costa then powers past Varane and smashes the ball inside the near post from the tightest of angles.
It did not look possible to score from there, but he hit it with such venom and accuracy that not too much blame can even be attributed to Navas at the near post.
1 min REAL MADRID 0-1 ATLETICO MADRID (DIEGO COSTA)
1 min Here we go, then! Atletico get us underway in Estonia!
