Borussia Dortmund use to be very consistent on there Bundesliga then but now a lot of things has changed about them, though Borussia Dortmund is well known in terms of generating a good players because the above listed names are currently doing very well on there current clubs.
Ever since I knew the Bundesliga, Dortmund has always been able to produce great players who go to big teams. In fact, they don't seem to have any intention of winning the league because they always sell their best players. But it seems that Dortmund has become a business-oriented club. As long as they are not bad in the League and have an advantage then they will not be a problem. It seems that supporters are also not too fanatical about the champion.
