Tension between Salah and Klopp carried over to the final whistle, as Liverpool’s leading goal-scorer headed down the tunnel without shaking hands with his boss, and it is that lack of interaction that is said to have started the argument. The Sun credits a source as saying: “This has happened occasionally with Jurgen and other players. He is very big on interaction with his subs before they go on and felt it didn't happen at first with Mo. Mo was obviously annoyed at being left out of the team and wasn't in the best of moods while Jurgen wasn't happy with his behaviour. The players were given a couple of days off after the match and are meeting up again on Tuesday. It is hoped that by then tensions will have calmed down.”
