Why Jules?
It was quite obvious that the players didn't like him and the owner gave him no time. The chelsea job is a poisoned chalice. AVB was a fool to go there this early in his career, but he can obviously make a team play attractive football.
Fabs, those bolded words are the crux of this. AVB may well be a very talented manager but his lack of experience and stature was a fatal handicap in a job that big, and the Liverpool job is every bit as big. However talented, he's simply not ready.
