Liverpool boss Jurgen Klopp admits Mohamed Salah wasn't up to expectations for Sunday's 0-0 draw with Manchester United.

The Premier League's leading scorer was hugely off form in the goalless draw at Old Trafford on Sunday, and was substituted to cheers from the home fans with 11 minutes remaining.

Klopp said: “Mo knows he can play better than he did today, we know he can.

"Two weeks ago we played against Bournemouth and he was unbelievable.

“In big games, against Bayern he was up against (David) Alaba who is a world-class player himself.

“It's about how we use him, how we play him, all that stuff. Today obviously (Victor) Lindelof and (Luke) Shaw together did a pretty good job."

Asked why the Egyptian underperformed, Klopp said: “I don't (know) exactly.

“But I'm not here to be disappointed. I'm here to help the players to play their best football.

“I'm not sitting here and saying that because we draw at Man United, all the boys are guilty. They want to perform 100%. Sometimes it doesn't happen."
