Chelsea manager Jose Mourinho has turned his attentions to Manchester United and Liverpool after the 2-0 Premiership win at Arsenal.
The victory leaves his side 20 points ahead of their London rivals.
Mourinho said: "The distance between us is now very big and we should not worry about it.
"But the distance between us and Manchester United and Liverpool meant a draw wouldn't have been good for us and we had to go for three points."
Goals from Arjen Robben and Joe Cole were enough to give Chelsea their first league win at Highbury since 1990.
And Mourinho was impressed with the Dutchman's contribution after a spell on the sidelines.
He added: "He made a big contribution to the three points.
"He has been very tired after the last three games but we had a week to recover and get him sharp and the result was very impressive.
"I was impressed with the whole team and we pressured them without even having a backpass right from the start. I think they were surprised by that.
"When Manchester United won at Aston Villa yesterday I became more confident about this result. I knew the players would answer in the right way."
