Antonio Conte’s side left it late but managed to overcome their struggling hosts thanks to a late Davinson Sanchez header.
For the second game in succession Conte’s Spurs side lacked attacking spark, although they did have decent chances for Pierre-Emile Hojbjerg, Sergio Reguilon and Harry Kane.
But it took defender Sanchez to break the deadlock in the sixth minute of stoppage time, flicking in a header from a whipped delivery by Son Heung-min. Minutes before that, play had been suspended after a medical emergency in the crowd.
Victory lifted Tottenham into fifth place, above Manchester United and West Ham United, with 33 points from 18 games, two points behind Arsenal who have played two games more.
It was cruel on Watford who have now lost six consecutive league games and sit one place and two points above the bottom three, having played two more games than 18th-placed Burnley.]
