Chelsea boss Carlo Ancelotti was delighted with victory at Burnley.
Ancelotti was happy to put some daylight between his side and Manchester United but accepted Burnley had tested his side in their 2-1 win.
He said: "It was a difficult game, especially in the second half. We were not able to play the way we liked and they equalised.
"We then put more pressure on them and deserved to win. We are four points ahead of Manchester United and that is good."
