Two goals from Eden Hazard kept Chelsea seven points clear at the top of the Premier League as they beat Manchester City 2-1 at Stamford Bridge.
Hazard opened the scoring when he converted Cesar Azpilicueta's 10th-minute cutback, before Sergio Aguero levelled for City after Thibaut Courtois parried David Silva's shot into his path.
The Belgian restored Chelsea's lead by scoring the rebound after his 35th-minute penalty had been saved by Willy Caballero.
Vincent Kompany, returning to City's starting line-up, headed against the crossbar before John Stones sliced over from close range in stoppage time.
But Chelsea held on to remain ahead of second-placed Tottenham Hotspur, with Man City fourth on 58 points.
