I am not sure what has been the problem with Juventus, but I guess Pirlo might not have been as perfect a boss as many would have expected... the fact that you are a brilliant player doesn't necessarily make you an awesome coach!
And just reading about those midfielders you described made me feel like something is wrong... you can't be among the best teams in Europe with such midfielders. You need class and stars! Guess the Super League would have been a nice gift to a Juventus who doesn't even manage to be in the top four in Italy. Of course, they might still end up in the top four, but I am not that convinced at all!
Yeah sadly it's very unlikely for Juve to be in the top four this year. About our midfielders I think that they have the potential to become very good midfielders and maybe something more. Probably I'll write a post about that as I think many Juve midfielders aren't very well known outside of Italy. However this year we would have needed an experienced top midfielder, that's beyond doubt. Sadly Khedira was always injured so we had to sell him but it would have been perfect.
