Tottenham survived a late West Ham onslaught to emerge with a 3-2 win from a ding-dong derby.
Harry Kane scored twice in four first-half minutes and Spurs appeared to be cruising when Christian Eriksen added a third.
But Javier Hernandez pulled one back before Serge Aurier marked his full Spurs league debut with a needless red card.
That left the visitors a man down with 20 minutes to go, and when Cheikhou Kouyate halved the deficit they must have feared another dose of West Ham woe.
The Hammers had, of course, inflicted near-fatal blows to Tottenham's title hopes in the previous two corresponding fixtures.
