Drury and Laviolette Must Go
Ter Stegen's problem is that most people in Germany don't see him play regularly, so their opinion of him is strongly biased towards the view established early in his career - talented but not 100% reliable.
It's a huge risk for goalkeepers in particular to leave the BuLi because of that factor. Out of sight, out of mind. Going to Barca allowed him to play in a CL final etc. but his standing in Germany would probably be greater if he had been with Dortmund that whole time.
You are probably right, but I don't even think it's that with the pattern of criticism from the Bayern hierarchy. I think they just don't want to admit that another German keeper is on the level of Neuer. It's not like these two have now both criticized Rudiger or Sane (prior to signing for Bayern). They criticized a player who directly threatens the starting position with the National Team of a Bayern legend.
