William Gallas' sit-down 'protest' at the end of Arsenal's last visit to Birmingham showed that he cared, according to Arsène Wenger.

The defining image from that 2-2 draw at St. Andrew's in February 2008 was of Eduardo, crumpled in a heap after suffering an horrific injury in the opening minutes. But close behind was the sight of an anguished Gallas, sat alone on the pitch after a stoppage-time penalty had earned ten-man Birmingham an unlikely point.

The then captain was criticised for his reaction but Wenger defended him at the time and he defended him again as Arsenal prepared for another trip to Birmingham this weekend - this time without Gallas, who is sidelined by a calf injury.

"People pick one isolated incident and they dwell on it and think it is all down to that," reflected Wenger.

"It was an incident that ideally you do not want to happen but I can understand Gallas' frustration. They get a penalty but if you watch the game it is never a penalty. In the last minute of the game. He was frustrated.

"On one side you want the players to care the maximum but on the other side you do not want them to go show any emotion.

"Sometimes he goes overboard like on that day. But Gallas cared and he did not behave the way he should have done but he did not behave like that because he didn’t care. He cared."
