Franck Queudrue insists Birmingham's players have the passion needed to come out on top in Sunday's derby with Aston Villa at St Andrew's.
And the defender admits that referee Howard Webb may brandish a red card or two if the desire to win what he calls “our biggest game of the season” boils over.
Queudrue said: “We all know exactly how the fans feel about this. They are on at us all the time about beating Villa.
“It is certainly our biggest game of the season. You can talk about Manchester United, Arsenal, Liverpool coming to St Andrew's but, no, this game is more important.
“The fans have passion for it, and as players you must have that passion too - and we have.
“It's about who wins the duels, the single battles, without being silly of course, but in a good way.
“That's who will get the game but the referee is going to have a tough job. He could have a problem keeping 11 on the pitch from us and them.”
Villa demolished Blues 5-1 in the last derby two seasons ago and effectively ended the hopes of their rivals clinging onto their top-flight status.
“We were relegated soon after that but we have a different team now,” added Queudrue.
