Bayern have a strict wage structure that De Jong is going to break (while he's not even going to be a guaranteed starter, even though eventually I think they'd settle on Kimmich - De Jong behind Müller). He's going to earn more than Neuer & Lewandowski and Rummenigge had shown time and again that he's not going to break that structure for anyone — even for someone like Alaba.
So yeah, City, us, Chelsea and, of course, there's always an option of Paris — they would love to sign someone for their back 7 of De Jong's quality.
