PSG has money, but no guarantee of winning the UCL trophy. Kane would prefer to go to the Arab League if his priority was only to get a big salary offer, the situation Kane experienced was not how much he was paid by the club he defended but where he could be guaranteed to win a prestigious title.
Bayern Munich is the best choice for him than PSG, he has no difficulty adapting to Bayern Munich style of play because he has Lewandowski characteristics. A player like Kane must be able to get what he has not been able to get with Tottenham so far, Bayern Munich is the most appropriate club for him to win a trophy which has been a dream for him so far.
It is very difficult to say how easily Kane can adapt to a league he is unfamiliar with, it will also depend on his relationship with the players, with the coach and much more, so it is difficult for me to say that it will be easier for him to adapt in Bayern than in PSG. Especially since Kane said that he does not want to go to PSG, he is only interested in moving to Bayern.
