Enzo Maresca revealed he is 'embarrassed' by Chelsea's lack of discipline and appeared to accuse Liam Delap of selfish play after the forward recorded the club's sixth red card in nine games.
Chelsea squeezed past Wolves 4-3 in a remarkable Carabao Cup tie but were not helped by the dismissal of Delap, who came on as a second-half substitute only to pick up two yellow cards in seven minutes.
Maresca offered no justification for the decisions and offered a withering verdict on Delap, who joined the club from Ipswich last summer for £30million.
