Eden Hazard scored both goals for Chelsea as they beat Watford 2-1 at Vicarage Road to move back into fourth place in the Premier League
Hazard netted his 100th goal for Chelsea in all competitions when he opened the scoring in the first minute of added time in the first half although, just over two minutes later, Roberto Pereyra equalised for Watford (45+3)
The Belgian scored his second goal of the evening in the 58th minute after he won a penalty, with Watford goalkeeper Ben Foster bundling him over in the area
 He then sent Foster the wrong way from the spot and ultimately sealed the win for Chelsea
It puts the Blues back in the top four in the Premier League table on 40 points after Arsenal's draw at Brighton had briefly seen them drop down to fifth
 Watford remain in ninth
Chelsea had the first chance of the game in the 11th minute
 Mateo Kovacic broke down the field before picking out Willian on the left flank
 The Brazilian then cut inside - getting around the oncoming Foster - before trying to slot home on the angle but Christian Kabasele was there to see it behind
 However, the Watford defender clattered into the upright with his armpit and was substituted not long after
Watford went close just after the half an hour mark, but a woeful finish from Abdoulaye Doucoure after a gut-busting run from Pereyra saw the ball fly high over the crossbar
 Chelsea then had a chance at the other end, but Hazard was not able to turn a fizzing Cesar Azpilicueta cross home, trying to use his heel to turn it home
But the goals came thick and fast as four minutes of added time were shown
 Hazard got his 100th Chelsea goal inside the first minute as Kovacic took advantage of a poor square pass from Etienne Capoue, picking out Hazard to the left
 The Belgian then rounded the oncoming Foster before slotting home into an open net
Just over two minutes later - 137 seconds to be exact - and Watford were level
 It came from a corner after Kepa Arrizabalaga did well to keep out Doucoure at the near post
 Jose Holebas delivered the set-piece, which found an unmarked Pereyra at the top of the area and he hit an arrowing volley through the packed box into the bottom corner
Chelsea retook the lead 13 minutes after the restart after being awarded a penalty as Foster bundled into Hazard in the area
 Hazard stepped up to take and sent the Watford goalkeeper the wrong way as he notched his second goal of the evening
The visitors continued to go close as the game wore on, with Willian seeing an effort ping off the post in the 72nd minute after a lovely cross from Hazard before the Belgian was involved again not long after with a storming Chelsea break
 He picked out Kante to his right, but with Watford defenders closing in, the midfielder could only send his shot past the far post
A minute later Doucoure put a lovely cross into the area for Troy Deeney - who had got ahead of David Luiz - but he did not catch the ball well and lifted it over the crossbar from inside the six-yard box as the game ended in defeat for Watford
"I think we've competed very well
 We conceded one in the first and then we scored our goal, and in a moment when we were playing better, we conceded the second goal
 It was difficult because we know they are a very good team but I think we competed very well
""I think that we played a good match with a good level of determination and attention for 90 minutes
 I think we could have won with another result, we missed three or four good opportunities in the last 20 minutes but I am really very happy with the reaction and application for 95 minutes
 Today we reacted very well while playing our football
"Who else? It was a vintage Hazard performance and he hit an important milestone with his century for Chelsea in all competitions
 He continued to show why he is so important for the west London sides, being involved in many of the attacks, and he could well have had a hat-trick
But with three shots, two on target and two scored, it was still a successful evening and a late Christmas present for the Belgian, with  pundit Alex Scott calling his performance 'absolutely superb'
Watford are back at Vicarage Road on Saturday as they host Newcastle in the Premier League while Chelsea make the short trip to Crystal Palace on Sunday with their 12pm kick-off live on
