Chelsea equalled a club-record run of 11 consecutive league victories with a 1-0 win at Crystal Palace that strengthened their lead in the Premier League table.
Exactly a year on from sacking Jose Mourinho for overseeing such a poor defence of their title, the Blues went nine points clear of closest challengers Liverpool and Arsenal with a goal from the rejuvenated Diego Costa.
It was in the 43rd minute when, with little obvious threat, Eden Hazard's pass played Cesar Azpilicueta into space on the right wing, and from there the Spaniard curled a superb cross towards Costa.
Under little pressure from Scott Dann the striker then casually headed his 13th league goal of the season over the goalkeeper and into the back of the net to seal all three points.
Liverpool and Arsenal retain a game in hand on Antonio Conte's impressive team, but they will regardless be top at Christmas and will likely remain there heading into 2017.
