Hope they give him a lifetime contract
Tbh considering the positions they're in, Dortmund has done much better than them ever since Flo took over
When they were up against us, they were bound to not win a great deal many leagues. It's infinitely easier to win a league when your rivals are Arsenal, Roma, Lazio, Wolfsburg, Leverkuzen, Marseille etc.
Even Atletico managed to pull a super-season out of their ass, and destroyed their league prospects this season as well. Winning La Liga the second toughest thing in club football.
Other than that, you cannot really fault them, they were miles behind us in only one season (Mou's last) and always make at least the CL semis. From there on then, there is a roulette element. Their UEFA coefficient is higher than us or Bayern's. That tells you about their consistency in Europe (and some easy draws to be sure)
And how can you compare Dortmund to Real Madrid? They have only made the semis of the CL once. They won't be in it next season. They won their league (a weaker and easier one than La Liga) only before BM became mighty.
People forget that Real Madrid managed to achieve their primary goal. Winning La Decima.
What makes them look far worse than they are, is simply Barca!
