West Ham defender Issa Diop was left frustrated after defeat to Tottenham.
Diop kept Harry Kane quiet, but the Hammers lost to Erik Lamela's lone goal for the visitors.
“It's very disappointing because we had chances and their 'keeper had a big game and Tottenham were more clinical than us," the centre-back told whufc.com. “That is what disappointing.
“It was the same game as against Brighton as we had chances, but we didn't score, so we need to work and I hope we will score more goals in the next game.
“I played normal, but we conceded a goal and we didn't win, so I can't be happy with my performance. I want to test myself against the best players and Kane didn't score, but we didn't score either, so we lost the game."
