Salah and mene are key players in Liverpool, if they leave for another club it will be hard to find players who can replace them that can play the role in the team. Liverpool needs salah and mene more than Anyone they would want. I don't think if this two players are leaving Liverpool next season, this are the kind of players Liverpool needs .
Salah and Mane are definitely important figures in Liverpool, and if they probably leaves. I bet Liverpool performance will surely drop next season. Am quite sure the team won't want to lost two of their best players at a time, if Mane choose to depart from the club, the management will do anything within their capacity to ensure they retain Salah. However, after Bayern Munich lost their key player Lewandowski. They basically need an experienced player like Mane to replace him.
