Steve Bruce says handling the 'madness' of the derby atmosphere on Sunday will be key to his side coming away with a result.
We go to Blues 11 points clear of our city rivals and with a strong record in the fixture, having not lost in the league since 2005.
And the boss believes taming the cauldron of noise inside St Andrew's will go a long way towards another positive outcome.
He said: "That's the most important thing to handle, the atmosphere.
"It will be red hot – they'll make it that way.
"It's who handles that.
"I've often said you play the game and not the occasion.
"You've got to rev yourself up, of course, but you've got to remember to play.
"Let's hope we can go and win the game with a flash of individual brilliance.
"The big ingredient for the derby is to play well on the day if you can and, with all the madness around you, to keep focussed on the game and play it the right way."

Bruce also admits he's said less to his players than normal this week, insisting the magnitude of the game does that particular job for him.
He added: "I don't think you have to do anything motivation wise – they understand.
"It's a big game, a big derby.
"What I didn't realise was the real intensity of it until I arrived in the city.
"It's always one of those great occasions.
"It's not always a great football match, but that's derbies for you.
"But in terms of entertainment and what's at stake – it's all to play for.
"It's why you're in the game, why I'm here – the big occasion.
"It also means a lot to the supporters, of course."
