The rumours of a possible rift resurfaced on the weekend after Mane was visibly upset when he was taken off for Salah in the Reds' 7-0 win over Crystal Palace on Saturday.

This is not the first time the Egyptian's partnership with the Senegal superstar has been called into question, with there being reports of a minor bust-up between the pair after a match against Burnley last season.

However, former Reds striker Peter Crouch says it's not a big deal if Salah and Mane do not get along as long as they perform on the pitch.

"Mane's face, having been substituted, was a picture. He was furious and rightly so, because when you smell blood as a striker, the last thing you want is to be taken off," he told the Daily Mail.

"Are he and Salah the best of friends? I doubt it. But it doesn't matter. I had strike partners who I knew never liked me. It never prevented me getting on with my job.

"Liverpool have won everything over the past two years and I would expect them to retain the Premier League, too, given the form they have hit.

"But don't kid yourself that a competition isn’t going on between Salah and Mane.

"Every forward player is selfish and these two will want to score as many goals as they possibly can — Salah, in particular, looks obsessed with his numbers right now."
