Premier League giants Liverpool may be without Alisson Becker for several games due to injury.
The Brazilian goalkeeper has sustained an issue that he picked up during their Premier League draw with Manchester City at the weekend.
Becker had been an ever present for the team in Premier League games so far this term.
Asked about Alisson and his teammate Diogo Jota on Wednesday, manager Jurgen Klopp said: "Both are out. Ali is a bit lesser, so we have to see.
Not day by day he cannot play tomorrow or Sunday probably not the week after, (but then) should be kind of okay.
"Diogo will take a little bit longer, don't know exactly. We have to see. Alisson not as bad (as we thought) but still bad enough."
