Liverpool boss Jurgen Klopp has confirmed Mohamed Salah will return to action against Genk on Wednesday.
However, Joel Matip and Trent Alexander-Arnold (illness) will miss the trip to Belgium.
Klopp told the club's website: "It's absolutely good to have him (Salah) back.
"The squad is cool, it's a good squad, everything is OK, but that's all."
He added: "Trent is ill and Joel is not ready.
"It is just a little thing which usually settles in the two weeks [Matip] had; it did, but then it came up after the United game and so now we just have to make sure this time it settles finally, that's all. It is not a massive injury, it's just a bit annoying for him and he cannot do it [face Genk].
"Trent got ill overnight; hopefully he can recover quickly, but for tomorrow there was no chance."
