Nigerian forward Alex Iwobi scored a resounding third goal as Arsenal cruised through to the FA Cup fourth round after defeating Blackpool 3-0.
19-year-old forward Joe Willock headed in after Aaron Ramsey's free-kick hit the post and tapped in another before half-time.
League One Blackpool struggled to keep pace with the Gunners, whose arrival at Bloomfield Road was delayed when a protestor sat on top of their bus.
But after Armand Gnanduillet went close, they improved after the break before Alex Iwobi's late finish.
The hosts had run Arsenal close during their fourth round Carabao Cup tie earlier in the season, which ended 2-1 to the Gunners.
But despite six changes to the Arsenal team, there was still a gulf in class from the start as Willock became the first Gunners teenager to score in the FA Cup since Ramsey - who ran the show here - in 2010.
Another teenage forward, Eddie Nketiah, could have had a hat-trick before the interval.
Any hope of creating a hostile atmosphere for the visitors was impossible amid ongoing protests about the way the owners run the club, which has seen fans stay away from games.
With 3,777 home fans present, added to Arsenal's 5,218, Bloomfield Road was half-empty as Unai Emery's side easily moved a step closer to adding to their record 13 FA Cup trophies.
