Chelsea rallied from a goal down to beat Manchester City 3-1 and stretch their winning sequence to eight Premier League matches.
Chelsea fell behind on the stroke of half-time when Gary Cahill deflected Jesus Navas’s cross over Thibaut Courtois.
Shortly after Kevin De Bruyne missed a glorious chance to double City's lead, Chelsea were level.
Diego Costa scored his 11th goal with a turn and shot on the hour and 10 minutes later Willian put Chelsea alead, celebrating by holding aloft an armband honouring the victims of the Chapecoense air disaster.
Hazard’s breakaway goal at the end decided matters before Sergio Aguero and Fernandinho were sent off.
