Arsenal manager Mikel Arteta has admitted Wednesday's clash with West Ham United is a "big game".

The Gunners are just two points off David Moyes' side, who are currently fourth on the Premier League table.

"For me they are one of the best teams in the league," Arteta said before the game. "The understanding that they have, the clarity in what they want to do and how much they are able to hurt teams with the way they play has been impressive and they have been really really consistent.

"It's a big game because of the position they are in, and the position we want to be in. Tomorrow we have the opportunity at home, in front of our people to do that. That would be a big, big boost.

"You can see when the crowd gets behind the team, the moments that [the team] are creating.

"A really great example was against Southampton, and that's what the players are talking about right now. They know tomorrow night under the lights they will be right behind the team and they want to please them."
