there is no competition between Dortmund and Munich
Bayern munich is a rich and selfish club that will purchase every great player from the other team from bundesliga. They bought the majority of dortmund's star player and there is rumour that they will purchase aubameyang as well after they sell lewandowski with a high prize to real madrid
ya right, bayern munich can be said to be cheating, always buy players from the team that could harm them. almost all the star players of dortmund always they take. so when bayern munich get the title bundesliga, it is a common and very boring. IMO
