Speaking to 'Sky Sports' after the game, the manager remarked:
"It feels good. Even if we didn't win I would be happy because we worked hard.
"We are happy and for our fans, it's massive, to come here and get three points.
"It means more for our fans. The way they travel, the way they celebrated at the end of course it's special because it was a tough game.
"It's one step more in the way we want to go.
"The moment of recovering the ball with two minutes to go was huge. After 90 minutes one of our midfielders went high to press and won the duel.
"We know about West Ham on the counter-attack, with the speed of the players, but we were fortunate to get on the counter-attack with the high pressing of Ruben and deserved it because the boys worked hard."
