He admitted: "I don't worry what they are doing. I am only concerned by the quality of my own team."
WENGER NOT WORRIED
"My players don't look at United that much. They know that the danger if we don't play well is that someone else might take our place at the top. It is not only Manchester United."
"It is no longer a case of capitalising on United's bad run because I know we can do even better than last season.This time last year we were not as good as we are now."
