Mane had many difficulties with Bayern Munich and was fined by them at some point, he failed to play as he used to do with Liverpool but I doubt they will accept him after his departure.
Liverpool still have to reinforce their lines including the attack line so they can get back to top spots again!
In my opinion, maybe one of the reasons why Sadio Mane struggled at Bayern Munich was because when he strengthened Liverpool, Sadio Mane had two tandems up front for Liverpool, namely Roberto Firmino and Mohamed Salah. the three of them were once one of the most dangerous striker trios in England and even in Europe by scoring many goals and providing many trophies for Liverpool. but last season Sadio Mane's performance declined at Bayern Munich maybe because Sadio Mane did not find chemistry with other Bayern Munich players, especially on the front lines such as Thomas Muller, Leroy Sane and Eric Maxim Choupo-Moting.
Sadio Mane is now rumored to be returning to the Premier League, but I don't think Liverpool is the goal. Better yet, Sadio Mane will save his career to Newcastle United. because if there he has a lot of time to play.
