Coventry manager Chris Coleman criticised the performance of referee Steve Bennett and described him as being ``smug'' after Chelsea gained a 2-0 win in their FA Cup quarter-final at the Ricoh Stadium.
The Sky Blues boss was furious that Bennett allowed two Chelsea players - Didier Drogba and Alex - back on the pitch so quickly after needing treatment and within 30 seconds the latter had scored the crucial second goal.
Coleman said: "I was disappointed with Mr Bennett all afternoon as were my players - his attitude towards us and towards them."
He added: "I know it was Chelsea who are a great team who deserve respect and he let us know that in no uncertain terms.
"That is not why we lost but I was disappointed with that. He was smug towards us, the way he was talking to my players, my senior players.
"He was very friendly towards some of the Chelsea players. I know they are great players but you are there to do a job and my players are not happy with his attitude.
"Then for the second goal Chelsea had two players off the pitch for treatment. You are not supposed to wave them back on until you see where the ball is going to bounce and so they gain no advantage.
"You can't wave them back on in a situation like that and who scores the goal - Alex."
Coleman added: "Chelsea paid us a compliment by fielding such a strong side.
"I couldn't ask any more from my players but we were disappointed with the first goal we gave to Drogba. We don't need to give them any help. They are good enough to create their own goals."
