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 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 before Batshuayi and then Azpilicueta instigated the turnaround. Batshuayi added his second in stoppage time.
Chelsea also had the officials to thank after Pedro's opener, a superb long-range strike, came from a corner that should not have been given.
