Yeah, I have that impression too. Weird bunch. Most of them seem okay with Bayern illegally tapping up their players and signing them for free or low fees.
Upamecano, Pavard, Cuisance, Arp, Goretzka, Sule, Wagner, Gnabry, Rudy, Hummels, Kimmich, Lewandowski, Gotze, Mandzukic, Dante, Neuer and Gustavo all signed from German clubs last 10 years. A couple of them for free too, such as Goretzka and Lewandowski. Bayern make sure there`s not any competition in the league and bully whatever club they like
