Not sure tho, if you look at the transfer window, most clubs have tight budget except bayern. I mean the bundesliga as a whole have a very strong home grown culture. which explain why their national team is so strong. however, not all generations are best, probably some downfall due to selling players and finding a new homegrown replacement. tactical wise a lot of great play in bundesliga. also the reason why if you see the club participating in europe have not been consistent. wolfsburg, stuttgart, werder bremen, schalke and leverkusen used to be in ucl and europa. rising club on the other hand like hoffenheim and leipzig is replacing them.
Is it me or german club seem to have tougher time than any other club in Europe? I mean, yeah, Bayern barely lost a game but both Leipzig and Dortmund have had trouble in the group stage and among the remaining team playing in Europe, the only teams to win by a margin of a single goal were Bayern (2-1 in CL vs Sevilla) and Leipzig (1-0 in Europa vs Marseille). Not saying it mean a lot but I don't, it could be those team are a bit more inconsistent (make sense for Leipzig with their young team) or that they have harder time than other team to adapt to other country playing style? What do you guys think? Is there a point in asking ourselve this or are the recent performance just a coincidence?
