After next weekend's home match against Brighton, Salah is set to depart for the Africa Cup of Nations and hinted that could be his final appearance in a Liverpool shirt should he be selected.

Former United and England striker Rooney believes Slot must now demonstrate he is in charge at Anfield by leaving Salah out completely from Champions League tie at Inter Milan.

"Arne Slot has to show his authority and pull him in and say 'you are not travelling with the team, what you said is not acceptable'," said Rooney in his BBC podcast.

"Take yourself off to AFCON and let everything calm down. If I was him there would be no way he would be in the team."

Rooney added: "He (Salah) is absolutely destroying his legacy at Liverpool. It would be sad for him to throw it all away. He's gone about it all wrong."
