A brace from Jonathan Spector and a brace from Carlton Cole secured a 4-0 win to the Hammers in the Carling Cup.
Grant told Sky Sports: “I’m not surprised because I’ve been with the players a long time and in some games here, the second half against Newcastle and the whole game against Liverpool, we’ve played well.
“Today we played fantastic and also scored and we kept a clean sheet. So I’m very happy. I thought we could win, but not by that score.
“It’s very special. To perform like this against the best team today in the country and score four goals, what more can I ask?”
Grant heaped praise on former Manchester United defender Spector after the game.
“I think he’s a professional guy,” added Grant. “He’s always trying hard, even when he didn’t play.
“Today he got the chance and like every professional player you need to speak only on the pitch – and he spoke very well today.”
