Yes, he will and Yes it was all about the money.
Honestly I respect his decision even if it was 100% about money. Whether you treat everyone the same whether you have to accept the underpaid guys to leave.
I can't work in a place where I am working hard and get paid half what the others receiving.. It is unfair.
If we take it from another perspective, AFAIK Mane is doing many charity actions in his native village, not sure how accurate that was but to say that he isn't "hungry" about the money.
Mane is not a money hungry player, he is one of the most generous football players, a lot of his money is spent on charity. The reason Mane moved from Liverpool was not because his salary was small, as long as Mane in Liverpool uniform has never been included in the list of the top three Ballon d'Or. Mane wants to find a new adventure to achieve his ambition to win the Ballon d'Or. Bayern Munich really dominates the Bundesliga, it's difficult for RB Leipzig and Dortmund to break Munich dominance, this Bundesliga giant is also successful in Europe. Mane can realize his ambition with Munich.
