West Ham boss David Moyes says the club is "blossoming" after his side beat Tottenham to climb into the Champions League places.
Michail Antonio continued his prolific form as he poked in the winner from Aaron Cresswell's dipping corner for his sixth Premier League goal of the season.
Harry Kane earlier saw his back-post header tipped over the crossbar by Lukasz Fabianski, but Spurs failed to capitalise on several decent opportunities.
The win moves West Ham to fourth in the table on 17 points, making it Moyes' best start to a season since 2004-05 with Everton.
