Chelsea look set to extend their lead at the top of the table thanks to three first-half goals against Norwich.
Fernando Torres had the first chance of the match when he was put through on goal but the number nine delayed for too long, allowing Leon Barnett to get back and clear.
The Canaries then took the lead through Grant Holt. The striker found the corner of Petr Cech's net with a precise finish following Alexander Tettey's knockdown.
Chelsea responded moments later when Torres made up for his earlier hesitancy by heading home Branislav Ivanovic's centre.
The Blues completed the turnaround midway through the half when Torres's acrobatic effort was blocked and Frank Lampard tucked in the loose ball.
The Blues got their third not long after when Juan Mata broke away and slipped in Eden Hazard, who slid past John Ruddy.
