I always figured that was their modus operandi. Buy good young players they don't really need so other teams can't have them.
"Wilkommen to ze German Rags, lad. Now sit here. Don't worry, you vill get playing time vith ze German Rags II team."
That might be ok for the real young talents that you land - but not for players like Gravenberch. The second team only plays 4th league - that is ok for a young talent that just comes from the youth team to get experience against men, but for a lot players getting loaned out is the next step if it is not hyper talented players like Musiala or now Tel.
He has to win himself a spot in the team - and with Kimmich being undisputeble starter no. 1 it is Goretzka, Gravenberch and Sabitzer fighting for the other spot. You should know it from your own team. There is about 2 players for every position.
We have Coman, Gnabry, Musiala, Müller, Sane, Erich Choupo-Moteng, Matys Tel and Mane fighting for four starting spots. Four players like mentioned for the 2 central/defensive midfield spot.
Gravenberch is new in the team - even came from an injury at the begin of the season. He is getting minutes in about every match - even if he just started 4.
Just as I mentioned him... After Davies and Musiala that is the next gem Bayern got - he will be good. Just 17. Came to Bayern from Rennes. Reel is from a test match against Red Bull Salzburg.
Not just dribbling but using his brain...
