Not the same at all IMO. They are a big club, but not in a big league, vital difference.
Top players are more likely to leave them then in top teams in the top leagues. They specialize in getting the better players in Bundesliga, when they sign quality players from the outside, like with Toni and Ribery, its due to the top teams in the better leagues not really going after those players. In overall, have more disadvantage then biggiest clubs in the top leagues.
