West Ham United manager Slaven Bilic has described his side's victory over London rivals Tottenham Hotspur as their "best performance" of the season.
Michail Antonio's seventh-minute header prevented Mauricio Pochettino's side from moving to the top of the Premier League table.
The result has moved the Hammers to within one point of Manchester City and Manchester United, who are fourth and fifth respectively.
"We expected this atmosphere tonight - it is the game of the season for us," Bilic told BBC Sport. "It is maybe our best performance. From the first minute we were on the front foot and dominant, tactically, technically and physically.
"Spurs concede the least goals and run the most so to out-play them is big and they should be happy it was just one goal they conceded. We changed the tactics with five at the back so we had wing backs chasing their runners and the system helped but how you play is more important. Our determination and togetherness was more important.
"We are not thinking about the top four. The gap might be small for those places but there is also a small gap between us and ninth place. We are going to continue to play like this and try to win every game."
West Ham are unbeaten in their last four games in all competitions.
