Gnabry is currently injured, Coman is injury-prone (missed 57 games since start of 16/17, only back to training recently), Muller plays through centre (and he's not that good this season), Goretzka is central-midfielder, Ribery most likely will leave after this season (end of his contract, Bayern' DOF said that they'll probably won't renew) and there's rumours that Bayern won't activate James' buy-option.
They're short of wingers and I think Hudson-Odoi has more chances to play for them then here.
