Why can the Bundesliga team sell its core stars to Bayern, willingly or under pressure?

If this kind of thing is not your feeling, I hope all the club players will agree, how can you succeed? Generally speaking, the players themselves are willing to go, and the club thinks that the price is right and sells it. Some people say that Bayern is poaching people and other clubs don't buy people, so why should Bayern poach people from small clubs? They also poach people from other clubs. Most of the Bundesliga internal transactions are dominated by German players. If you don't want to go abroad, of course you want to go to the Bundesliga overlord. Who doesn't want to be better, it's good for clubs to make money, especially smaller clubs.

Just like buying Neuer, Hernes said in an interview that he can wait another year and let him transfer freely. However, Bayern, as the leader of the Bundesliga, has to pay a certain price, especially for a strong but financially difficult team like Schalke. This is Bayern's obligation in the Bundesliga, which is also conducive to the development of the Bundesliga. .....
