Chelsea were favourites last year because their players were playing up to their potential, and it was before Cesc completely fell off the earth along with Ivanovic and Terry. All three of those players were instrumental in Chelsea being as strong as they were. They are disjointed now because it really affects the team to not have those pillars working as they were, and while their squad is very talented a steep decline in key players caused some very poor form, and with it poor morale. The circus with the doctors and Mourinho didn't help.
Obviously Mourinho isn't getting the best out of them right now, but I still think the players are being whiny primadonnas for acting as they are under him after winning the title just last season as well as the COC.
I have no sympathy for that team though so let the good times roll.
