Bayern Munich hopes are certainly on Mane. As a replacement for Lewandoski. But Mane has had a difficult season. Had a good debut, but in some matches Mane performed poorly and even argued with Sane in one team. But Mane jiga is not bad, he can score 12 goals and 6 passes. So I think he just needs some adaptation time. But I don't understand if he will stay or leave. I saw on social media that he was in demand by clubs from Saudi Arab.
Mane wasn't comfortable at all with Bayern Munich at a point he received a fine from them because of that. His performance dropped and he is getting annoyed to keep playing in Bundesliga in my opinion. I read weeks ago that he was thinking about moving out of Germany. I think he wants to get back to England and he might move to Saudi Arabia if they offer to him a good reward.
