Chris Powell's side head into tomorrow's game off the back of a solid 3-0 away performance against Oldham Athletic on Tuesday night...
The win gives Blues a boost which could prove vital when they take on Bradford who are currently unbeaten in their last four games and chasing a play-off place.
Despite this, the Blues boss is positive that his side can pull out all the stops to halt their recent run of form.
"They've picked up points recently but previous to that they've had a real tough time and I know Simon and he's been very, very successful at this level because he know's what it takes.
"They had a few injuries with key players and they've played all sorts of systems in the season.
"But they've settled down now and they're a side that will put us under pressure and they've got some players in key areas that can hurt you, and we are going to have to deal with that.
"Equally we are going to have to put them under pressure and carry on from where we left off on Tuesday because we are in a decent place, but I suppose while there's a slim chance for them they'll go for it [the playoffs] because I would and I think every other manager would.
"They've got a big stadium and they graced the premier league a few years back, now they are trying their hardest to get back and it's up to us to go there and spoil the party."
In recent games, Blues' forwards have hit the target and Powell believes that's down to the presence of Theo.
"Each player has their attributes and all of our front men are very very different.
"Theo is a box player but he's on the shoulder and one thing defenders don't like is running towards their own goal, facing their own goal and pace.
"Regardless of who you are you have to make decisions with or without the ball and that's what we've been looking for throughout the season.
"But Theo definitely plays his game between the posts and he showed us with his hat-trick [against MK Dons] that he's a goalscorer who know's how to position himself and his second goal in the game was superb play between himself and Michael Timlin.
"He's come in and showed that he can score all types of goals and he's obviously added to us and in turn I think that's brought out more in our attacking play, in our attacking third and I think it's influenced other players, Simon and him have dovetailed really well and it just so happens that Coxy gets two goals [against Oldham] which is a reward for his display.
"He [Theo] has stretched the play and has worried defenders and definitely at this level it's something that has added to our game as a team."
