Odion Ighalo could not add to his 14 Premier League goals on Saturday as Tottenham Hotspur edged Watford 1-0 to move into second place in the Premier League table.
Defender Kevin Trippier scored the only goal off a Dele Alli assist.
Defeat for Manchester City earlier in the day opened the door for the Lilywhites to move up one position, and they were able to do exactly that thanks to a sixth win on the bounce in all competitions.
Spurs dominated the game throughout, but it required Trippier’s goal 25 minutes from time to make the telling difference and keep their title hopes well on track.
The visitors set themselves up with five players in the middle in an apparent attempt to stifle Spurs’ attacking threat, which largely worked for the majority of the opening 45 minutes.
Harry Kane was able to get a brief sight of goal, which Heurelho Gomes was equal to on his return to North London, but it was a case of the home side remaining patient in their build-up play.
That Gomes stop provided a sign of things to come, as the Brazilian was alert to deny a lively Ben Davies down the right on a couple of occasions, while Erik Lamela also saw his long-range drive routinely kept out.
Watford looked to be on the ropes at that stage, having already seen Mousa Dembele blast narrowly wide moments earlier, yet the key breakthrough goal did not arrive prior to the break.
