Antonio Conte had shivered through much of this contest, hands planted deep in the pockets of his puffa jacket and that distant, rather haunted look in his eyes which tends to mark out Chelseamanagers under the cosh. The Italian had been emotionless as Eden Hazard belted his team level eight minutes from time and, perhaps more significantly, just as motionless as Watford ran riot in what time remained. A third chaotic defeat in four games has reinforced the sense this campaign is veering away from the champions.
