"They were well-deserved wins," he said.
"We were the better team again, there was no doubt about that. We created all the chances and deserved the points.
"The Man United result went our way tonight but you have got to take advantage of that. We had to make sure we won to get the benefit.
"It's a difficult task beating Chelsea, not many teams manage to do that."
