Arsenal boss Arsene Wenger had no excuses for their shock defeat by West Bromwich Albion.

Three second-half goals from Peter Odemwingie, Gonzalo Jara and former Arsenal player Jerome Thomas put Albion in dreamland before Samir Nasri scored two late consolation goals for the home side.

"We were poor and we got a poor result," said Wenger. "We were poor everywhere, at the back, up front and in the middle of the park.

"We had an off day and were not good enough to win the game. I believe the concentration that gives you the sharpness was not there today.

"We made it more difficult because we were not at our usual level, defensively or offensively. Anything was difficult for us today, to pass the ball, to win it back.

"Overall we got what we deserved, that is zero points. We didn't deserve more."
