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
Well even though Bayern Munich is a rich club with good management, we couldn't say it is a cheating. Bayern sometimes help to solve financial problem of other Bundesliga clubs even Borussia Dortmund, thats why its not a big matter for them to sell their players to Bayern. Anw that would be great if there are some investors who want to invest their money in Bundesliga clubs. I think thats the only way to make Bundesliga become more competitive.
