Michy Batshuayi came off the bench to score twice as Chelsea fought back from behind to win a six-goal thriller against Watford.
Chelsea were on the back foot for much of this contest at Stamford Bridge but two late goals from Batshuayi, either side of an 87th-minute header from Cesar Azpilicueta, snatched the champions a much-needed 4-2 victory.
For a while, Chelsea looked on course for a third straight Premier League loss when Abdoulaye Doucoure and Roberto Pereyra's goals put Watford 2-1 up with two goals either side of half-time.
But, despite a largely poor showing, Chelsea remained in the contest and game-changer Batshuayi and then Azpilicueta instigated the turnaround, with the Belgian striker added his second in stoppage time.
