No one doubts the charm of bayer munchen towards football players, I think when munchen has want and is eyeing a player of course it will be difficult the player to resist , promising a championship title and also a high salary is one of the attractions that munchen has at this time, that is why when there are players who leave munchen it doesn't make the team falter because they will easily get substitutes who are just as good, so it's not surprising that Gravenberch will prefer bayern munchen instead of following his former coach to play at manchester united, in my opinion it is Gravenberch who appears quite slick and having a good performance with ajax last season will be a good addition in the middle sector of munchen next season.
I do not think that it is that simple. Don't get me wrong, they can get players how wouldn't be paid more in other clubs, but if there is a player that can get paid tens of millions of dollars from another club, then it is impossible to convince that player to go to Bayern.
Look at Mane, he is getting paid peanuts compared to how amazing he is, and that is why they are willing to pay a bit to get him, and then keep paying him peanuts, because that is all they can offer. If another club came out and said they will pay 50 million to get him, and 15-20 million for 3 years to him directly, then Bayern would have zero chance. That is the biggest difference.
