Arsenal boss Arsene Wenger was delighted with his team's powerful 3-0 win at Birmingham City.
A Robin van Persie free-kick and Samir Nasri's 13th goal of the season put the visitors in control before an own goal from Roger Johnson added to Brum's misery.
"I am delighted because we have shown physical qualities, we were up for the challenge and mentally as well we kept our calm," Wenger said.
"We kept faith in our game, that we could put the ball down and play our game. I feel we have had a great performance."
