Bayern coach can think of other options to keep Mane in the starting line-up because Sadio Mane can also play as a center forward or on the left or right wing, I have no doubt that Mane will be in the starting eleven, his quality is very good.
I think Bayern's forward line will be terrible next season if they are able to keep Lewanadowsi.
If they keep Lewandowski and also Serge Gnabry (because its possible maybe he will leave Munich) they will have an awesome great forward.
Mane not only can play 2 diffrent positions he can play on 4 and that makes him today unique and that changes the play system.
I have no doubt that he will be getting into the starting and playes from beginning , all other would be a surprise if only comes from the bank.
