History tells a different story
1970s Bayern vs. Mönchengladbach
Early 80s Bayern vs. Hamburger SV
Late 80s Bayern vs. Werder
90s Bayern vs Dortmund
2000s Bayern vs Leverkusen, Schalke and Bremen
10s Bayern vs Dortmund.
No club has managed to stay on level with bayern for longer than a decade (and that was only Gladbach). I´m not sure, that Dortmund is there to stay. Their success is based on a golden generation of young players and some clever signings from Poland. Plus a genius like Klopp to build a team around them.
But how long will this last? Their current U 19 and U17 teams are less than average, Schalke, Bayern. Wolfsburg have far better U19 teams, Schalke Stuttgart, Hertha, 1860 will play the u17 finals this year. Will they start buying star players? Klopp never worked with stars other than that he made himself. And how long will he stay at the club?
