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 when he slotted in the rebound after his 35th-minute penalty had been saved by Willy Caballero.
Vincent Kompany, returning to the starting line-up for City, headed against the crossbar before John Stones sloiced the ball over from a few yards out in stoppage time.
But Chelsea held on to remain ahead of second-placed Tottenham Hotspur, who completed a late win at Swansea City, with Man City fourth on 58 points.
