Sack Boas?,no not yet. However,Chelsea F.C. is at a certain level in world club football,it took years of graft & millions of pounds to get there and expectations are now, understandbly high.It's simply not exceptable for a club who 2 seasons ago won a double to be content with the Europa League,that's just the way it is. I've wondered how well his Europa League winning Porto side would do in the Premier league?,how would the players adapt?,more importantly,how would AVB use them?. My point is,if he's stuggling to impose his beliefs on the squad he's inherited at Chelsea,then doesn't he then have to adapt his beliefs to something that works even if it's for the short term?,isn't that what management is about?. I want him to have the chance to learn how to be a great manager in the harsh world of the Premier League,he could be brillant for CFC,but he needs to be a bit more 'savy' with his squad IMO.........its evolution not revolution thats needed.
