Birmingham were awarded a last-minute penalty and, in protest at the decision, Gallas retreated to the halfway line and sat down sulking.
The result was seen as a pivotal moment in Arsenal's faltering title bid and Gallas acknowledged he made a mistake with his actions. He believes some of the criticism aimed in his direction was unfair, but is confident he still has the backing of his team-mates to be Gunners skipper.
Gallas told L'Equipe Magazine: "The controversy about my captaincy? People had to find a scapegoat as we didn't win any trophies last season. "So, they talked and talked again about the Birmingham match. Indeed I made a mistake. I must admit I flipped my lid. We should have won that game easily.
"Before Arsenal, I spent six years at Chelsea. That team was capable of getting ugly wins. If we had an opportunity to win a cup, we would never miss it. "There I became imbued with the winning culture, which doesn't exist yet at Arsenal.
"Of course, some of my Arsenal team-mates could not have appreciated my behaviour against Birmingham. "I had to state my authority again and today when I motivate them before a match, they say; 'Capi, we need you, we are following you'. "If I would have been an unworthy captain, they would have banned me.
"The critics went much too far. Maybe I put myself under too much pressure, like Arsene Wenger said. "I believed I had a message to give to my team-mates and I could not find the right words.
"Our game made people dream, but we had empty hands. We have to show a more clinical state of mind. At the end of last season there was such a frustration inside me!"
