Will he get higher salary with Bayern Munich than get from Liverpool last season or he has another reason why leaving Liverpool.
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.
I'm sure that money was a maximum in second place for Mane. Judging by his interview, he has huge ambitions and he (in my opinion, quite rightly) believes that he will be able to realize them in the best way in Bavaria, after all, in Liverpool, thanks to team features and Salah, he was not the first violin. And I heard that he spends a lot on charity, this is another confirmation that money is not the main thing for him.
There is a possibility that he needs a title, especially the Champions League so he can try it through Bayern Munich you can imagine how he felt when he failed to become a champion in the final even though he has made every effort with all his abilities. In addition maybe he needs a new challenge, for 6 years Mane with Liverpool while he will retire in less than 5 years so this season is the right time for him to move.
