I was very sure that the Mane - Sane issues then will not keep Mane in the club. I have known Mane as a gentle guy all while but till now I have never known the true reason Mane hit Sane. But I believe that Mane had endured it very much before he acted.
But according to the previous comments, I really thought that Mane has future in Europe for one or two seasons. There is no doubt that he is 31, but he looks energetic to be in competitive league for more 3 seasons.
The last news, that i have heard was that Mane has also agreed now to go to Al-Nassr. Until now he insisted to stay at Bayern Munich as far as i know and he did not want to go to the Saudi Arabia League. Now it seems like the officials of Bayern Munich and Al-Nassr were able to convince him that a transfer makes sense. I guess that Al-Nassr is offering him a huge salary. Now the only thing that needs to be done is that both clubs need to find a solution. I would guess that Bayern wants to have at least 30 Million € as transfer fee for him, given the fact that the Saudis are throwing around their oil money anyway so a few millions more won't hurt them obviously.
So, after not being included in Tuchel's scheme at Bayern Munich, now Mane is thinking about leaving, this is the right decision he can make. Initially, Mane wanted to stay in the Bundesliga, but after a change in policy from Tuchel that he was no longer included in Bayern Munich's scheme, now the Saudi League will be his first choice. I think Saudi Arabian clubs like Al Nasrr will not be bothered with the transfer fee issue because as we know they will not buy players for such a low amount so it is undeniable that several top European clubs are interested in selling some of their players. I heard that previously Bayern Munich were willing to accept the release of Mane for 17 million but now reportedly they are thinking about seizing the opportunity and then Bayern Munich has now raised the price clause to 32 million because they know that what Mane wants is Saudi Arabia. Arab club is famous for its wealth. Looks like a deal is about to happen.
