Liverpool could be without their manager for the crucial UEFA Champions League clash against Napoli at home.

The Reds must win by two clear goals if they are to progress in the competition.

Now there is a danger of Klopp being banned by UEFA, given his overly critical comments about the referee after the 2-1 loss at PSG.

In post game interviews, Klopp said the referee made his side "look like butchers" by dishing out six yellow cards.

Klopp even said "a referee needs to be prepared for a game like this and he looked not prepared."

A fine is almost certain, but a touchline ban is not out of the question.
