Dortmund is the opposite of Arsenal, Arsenal are like 4th highest earning footie club, and should be financial giants, but have zero ambitions nor any will to spend that fortune (one of their owners is 28th richest man in the world, richer then pretty much everyone in footie). Dortmund in comparison has in well planned project from the last 4 years taken itself from mid-level status in German League, to a dominating force, this is all despite being quite behind financially to those they bested domestically and contentinal stage (though they are getting there with continued success), financial reason is why their players are leaving (while Arse dismantled itself due to total lack of ambition). You compare them to Arsenal, while I read Dortmunds team salary budget is LESS then Aston Villa's.
