I agree about Levy, he's made some mistakes but overall he's done a pretty impressive job.
As for Chelsea spending astronomical sums, well potentially by the end of the window yes. For now it's just the £32 Million for Hazard. Quite a big sum, no doubt, but one player isn't going to be enough to perform every week in the League like you need to. Last year we just never got started, every game looked difficult. Next year we won't have Drogba either, so astronomical sums do need to be spent if we want to go for the title, they've just not been spent yet
