West Ham captain Mark Noble insists victory at Manchester City was no surprise.
The Hammers defeated league leaders Manchester City 2-1 on their own patch with first-half goals from Victor Moses and Diafra Sakho.
The Irons humiliated Arsenal and Liverpool on the road in recent weeks.
Noble said: “We knew we were going to come up against it. They haven't conceded a goal. We watched the Juventus game and took some belief from that. We were nervy at the end but we managed to hold on.
"There are some tired heroes in our dressing room. We went into the season with a new manager, staff and players and we are slowly gelling together. We knew we had enough to get results like this.
"Bobby Zamora always used to say to me to get it and give it to the good players. That makes life easier for myself."
