There is no such News as same coming back to bayern munich he just Left Bayarn Munich two weeks ago I think that that must be a misinformation people should try as much as possible to verify the information that they put forward here there is no way that Galatasary will let a player go that they have signed
What you said is true, because every player has a contract with the team that signed them, so no player can just leave to any team they like if they're still under contract with their old team. However, being loaned to another team is different, as that team may already have more players for a particular position, so it wouldn't affect the loan move. I've also seen no news about Leroy Sane returning to Bayern Munich after being signed by Galatasaray last month.
