I don't think it's correct to say that it has crashed. Once the rise to the top turned to an extremely potent, succesful side, they got milked for talent and had to reproduce. Now they lose their best few players regularly, and have to replace them with exciting potential. They also lost their head honcho, who was probably pulling a lot of important strings in the clubs. Things like that will cause a fluctuation in form and results. It doesn't change the fact though, that they are still an exciting team, mostly challenging Bayern in Germany, mostly doing well in Europe. And they do well while developing new, exciting talent. To me, that's the way to do it.
