Arsenal boss Arsene Wenger was surprised Alex Song's 'goal' for West Ham United was denied yesterday.

The incident occurred when Song struck an impressive volley from 20 yards out that beat Arsenal's Szczesny, only for the linesman to rule it offside. When Song struck the ball three West Ham players were in offside positions but none of them touched the ball.

"I didn't know why Alex Song's goal didn't stand, I thought it would," Wenger told reporters. "We scored a good second goal and had many opportunities to score another. It didn't come and at 2-1 I thought the last 30 minutes would be difficult."
