The Reds face Derby tomorrow, a game that Klopp is expected to ring the changes for.
But Sakho hasn’t even travelled with the squad which will train at St George’s Park tomorrow morning.
Liverpool boss Klopp is still not happy with the Frenchman’s fitness
The France defender has not played since March due when he was wrongly accused of failing a drug’s test before suffering an Achilles injury.
Klopp said: “He is still working on his fitness.
“He is closer, but there is a big difference between match fitness and everything.
“It is not about how the player feels, it is about close I feel he is.
“It is a long, long time since he played and all the other players have not had a long break so it makes more sense if we use them.”
Roberto Firmino is in line for a recall after missing Friday’s Premier League win over Chelsea at Stamford Bridge.
“Roberto is in training,” said Klopp.
“The medical department told me he could have played against Chelsea, but I have heard the word risk too often so I decided no. I was very happy that it worked out.
“They told me if I gave him three days he would be perfect. Today is the fourth day.”
