Liverpool midfield ace Philippe Coutinho is going to be out of first-team action for more than five weeks due to an ankle injury he sustained in their Premier League win over Sunderland on Saturday.
The Reds manager Jurgen Klopp has confirmed the Brazil international was sent for a scan at Spire Hospital on Merseyside after being substituted during the first half of the tie against David Moyes' Black Cats.
Speaking ahead of Liverpool's EFL Cup quarter-final win over Leeds United, Klopp told BBC Radio 5 live: "Phil needs between five and a few weeks until we have him back. We will see. He is not in for tonight and for the next few games."
Klopp added: "Phil Coutinho is a really good football player. So if we cannot use him for the next few days or weeks, each team in the world would feel it, that's how it is.
"But of course I can say now there is no excuse for anything. As good as he is, he cannot decide games by himself, even when it looks sometimes like this because he takes the ball, dribbles and shoots.
"But then it's only a goal or whatever, then everybody has to defend so it's really a team performance that we create.
