Former Arsenal striker turned pundit Ian Wright believes that Chelsea's quest to win the Champions League is what has caused their bad league form.
Wright believes that manager Conte has an obsession with winning the Champions League, given his Juventus side's poor displays in the competition when he was manager.
Wright said: "It's all been brought on by Conte. He's not got what he wanted and almost thrown his toys out of the pram a little bit.
"In some ways that has got to the players because he's almost saying 'you're not good enough for what I want to do'.
"Something has seeped into the players because when you reel off the names of the teams that have beaten Chelsea, with no disrespect, Chelsea should have beaten them.
"It has been brought on by the manager. He has, for want of a better word, put that disease into the squad and their minds are not right.
"They should have beaten all those teams. They have shown against Barcelona they can defend so well and it was a mistake that cost them in the end.
"That team is much better than they are proving at the minute."
