Despite Mane's decision to leave Liverpool, Mohamed Salah is likely to stay with Liverpool next season. If Salah and Mane had left Liverpool together, it would have been difficult for Liverpool to have a stable performance next season.
Liverpool do not lose two players at the same time. They make an effort to keep at least one of them in the team. Mane has made up his mind to leave the team. He is not at Liverpool mentally. It won't be easy to keep him in the team any longer. Liverpool should take precautions to avoid the same things happening to Salah. Otherwise, Liverpool's offensive line will be very weak.
