Chelsea's 100 percent home record ended as a solo strike by Nedum Onuoha and second-half goals by strikers Asamoah Gyan and Danny Welbeck earned Sunderland a deserved victory. They were the first goals the Blues have conceded at home this season.

Bacary Sagna and Cesc Fabregas were Arsenal's goal scorers at Goodison Park, with Tim Cahill's 89th-minute consolation coming too late for Everton.

Arsenal is now just two points behind Chelsea, with Manchester United — which drew 2-2 at Aston Villa on Saturday - a further point behind.
