Nice post @hive-world.
With all this huge spending, I still don't know why Chelsea are still feeling very shaky in most games, even though they where dominant during preseason.
From my opinion, I think Chelsea needs to start a process where the club has to be reformed. The idea of sacking and consistent changing of managers won't help much, so a new process has to start, which they must trust.
Those players are very young and they have not understand themselves.
Sacking and changing of coach is one of the major factors the club is like this.
