Mane is an amazing players and he wanted to leave Liverpool to find a new challenge and that was a big mistake. He wasnt good with Salah outside of the field. If that fight with Sane didnt happen in Bayern i think we would be still watching Mane playing all the game for Bayern Munich. Hopefully he finds a good club soon.
It is his own right to leave Liverpool, we can't blame him that he made a mistake.
When he was in Liverpool, he already played a long time with Salah. That's why they can be a good combo wingers. While in Bayern Munich, they may have a different tactics and Mane may not know well other wingers' nature (play style). That makes him not very shining in Bayern Munich. However, I think he deserves to stay in Bayern Munich, he only needs time to adapt with Bayern Munich. But if wants to move, there should be many clubs interested in him since he is a great winger (has speed and good shooting accuracy).
We can't blame anyone here about this because Liverpool management was looking for cut in salary, but Sadio Mané was not agreed with this cut, so he asked for leave and then Bayern Munich jump into this which was looking for the suitable replacement for the Lewandowski but nothing positive happen for the all three parties but now as have all reports Bayern Munich is already cut him from their first team and ask for the transfer hopefully things will be good for him and his future.
Currently, two Premier League clubs are in negotiating about this possible deal but who is going to complete this is not official with the already rejected possible Saudi League offer because he wants to live here in Europe for the competitive soccer, but all possible things are available because if he has not suitable deal here in Europe then surely he will move for this as well.
