I think it might be more than that. We have a couple of players in Germany who get elevated to extreme heights and scrutiny very quickly and then the public holds them to that standard for the rest of their careers. Schürrle probably peaked at Mainz or Leverkusen and normalized to the level of a decent Bundesliga player, but clubs like Wolfsburg and Dortmund kept signing him for €30m and expected a corresponding return - his record for the national team didn't "help" in that regard either I guess. Whatever he did it wasn't good enough. "He did okay, but for €30m you expect more", I don't think anyone ever seriously doubted his motivation, but still I hope he never read the things people wrote about him online, people are sometimes quick to forget that you don't become a robot, just because you earn filthy amounts of money...
Götze has a similar dynamic, several notches higher even and if he were to retire tomorrow I wouldn't be surprised.While I don't find him particularly likeable I have a ton of respect for how well he appears to deal with the insane pressure he has to be under, e.g. his first return to Dortmund, warming up in the catacombs, because of 70k people who used to "love" him expressing their hatred and then he comes on and plays as if nothing is going on around him, scores a goal even. Draxler is another one, he probably did the right thing in leaving Bundesliga. Schalke in particular did a number on him by elevating him to messiah status before he was allowed to drive a car.
