Actually, I don't think Mane said he wanted to move to another team next season, but it was Liverpool's decision to sell him to Bayern Munich.
Are you sure about that, reports have it that it is Mane that is seeking an exit from the club, it looks like he wants to try a different league and a whole new challenge and competition, honestly i can't see a reason as to why Liverpool would make a decision to sell Mane, he is still delivering superbly for the club, his performance didn't drop even the slightest bit as well. It has to be that it is Mane who wants out. I could still be wrong, but that is what i honestly feel is going on with this Mane transfer news.
