On a night that Chelsea would rather forget, losing 4-1 away at Watford, the Hornets’ new loan signing, Gerard Deulofeu, marked his debut with a goal.
The match started slowly but gradually built to a crescendo, due in no small part to Tiemoue Bakayoko’s two yellows, and subsequent red, in five first-half minutes.
A man down, Chelsea were soon a goal down, Troy Deeney converting a penalty for the hosts just before the break.
With eight minutes to go, the Blues’ talisman, Eden Hazard, looked to have earned his side a point, but Chelsea went to sleep.
Daryl Janmaat (84), Deulofeu (88) and Roberto Pereyra (90) helped themselves against a team that look devoid of confidence with Barcelona on the horizon.
