Tottenham beat the Hammers 1-0.
Tottenham picked up their first victory in eight games to leave West Ham with a battle to stay in the Premier League.
Czech midfielder Tomas Soucek inadvertently converted into his own net following Giovani lo Celso’s corner and Harry Kane broke clear to stroke in his 18th goal of the season.
Tomas Soucek became the fourth Czech player to score a Premier League own goal.
With seven games remaining, the loss leaves the Hammers outside the relegation zone but only on goal difference with Bournemouth.
Aston Villa and Norwich who lie in the bottom three all now having a game in hand over David Moyes’ side.
The hosts punished toothless West Ham, who threatened little but saw Jarrod Bowen strike a post as they pushed in vain for an equaliser before Kane struck.
Spurs boss Jose Mourinho will be delighted with a victory that takes them just six points off the Champions League places and with Kane’s goal, which was taken with his usual aplomb after he was put clear.
It was also a sign of his increasing assurance in only his second match since a hamstring injury on 1 January.
