West Ham boss Slaven Bilic admits beating Manchester City was a "surprise".

City's run of five successive league wins without conceding came to an abrupt halt as Victor Moses and Diafra Sakho set up a 2-1 win the for the Hammers at the Etihad Stadium.

Bilic said: "It is a surprise, let's be honest. This game was different from Emirates and Anfield. With the greatest respect to Liverpool and Arsenal, this team (City) are the best in the league.

"We knew we would have to score goals to get something, we knew we would have to run like crazy, and we knew would have to be lucky. It is very difficult, if not impossible, to stop them for 90 minutes but we have done it.

"We didn't nick it. It would have been fair if they equalised, but we also had chances.

"That is why I am so proud of our performance. The guys have done brilliantly, not only fighting-wise but also playing-wise."
