Tuchel looks like he will completely overhaul his team for this season. several players are reportedly ready to be released including Mane. and maybe this is also one of Munich's efforts to bring in Kane.
If Sadio Mane will really leave Bayern Munich again after only 1 year, then i think this was definitely one of the most disappointing transfers of Bayern Munich in the last decade. Mane was an absolute world class player at Liverpool and when the first rumors started to appear last year that Mane might come to Bayern Munich i think many did not even believe it at the beginning. Then he really came and the expectations where extremely high obviously. Sadly it did not work out at all, at least not in the last part of the season. At the beginning everything was ok i would say.
If Bayern will sell Mane then they can save his very high salary of 22 Million € per year. This is even more important than the transfer fee they will get for him.
