I agree with that, should have worded it better. Bayern would be Bayern even without signing rival players as you guys are big enough and well run, however moves like that have weakened your challengers to the point where bundesliga is a foregone conclusion.
Its also why I found monaco "helping" PSG with the FFP for Mbappe weird, you dont help your rivals like that.
You find it weird because you don't take into account the fact that Monaco help themselves, not PSG. They have their own FFP problems to deal with.
