We gave it away cheaply - Sunderland's Bruce
The Black Cats were thoroughly outplayed by the Blues and Bruce says the result was not helped by the fact that his side were sloppy against dangerous opposition.
"It was very difficult against a very good Chelsea team. They had terrific possession of the ball and we spent that much energy trying to get it back," he said.
"That was the one thing that disappointed me - when we had it, we gave it away too cheaply and that made for a very difficult afternoon."
