Kingsley Coman never any injury record before he joined Bayern, he started to develop that when he joined here.
Vidal barely had any injury record at Juve or Bayer before he joined here, he started to get injured a quite some times when he joined here.

This cant be a coincidence

Robert Lewandowski got injured only once at Dortmund, after he joined Bayern, he has been injured 11 times.
There is something really wrong with the medical team. Since 2014 players have got injured out of the blue.
