The Blues picked up their first victory of the season in the Championship clash.

Goals from Jacques Maghoma and Michael Morrison came either side of Hadi Sacko's strike for the home side to hand the Blues their first win of the season.
And Rowett suggested that applying pressure to Garry Monk's men from the early stages helped create a sense of unease amongst the supporters, which in turn, led to the away side staying on the front foot in the contest.
"It's always important here," he told the Mail.
"We said this last year. Particularly with a minutes applause before the start, it builds a little bit of crescendo.
"It was important that we forced them into mistakes to quieten the crowd down a bit. Then you saw us feed off that lack of energy which is what any good away side should do."
Although the results in their two league games have been hugely disappointing, the squad that Monk has assembled arguably boasts plenty of players who have the potential to create some excitement that generates a buzz amongst supporters.

And generating that kind of atmosphere could ultimately be what inspires the Whites to put those two results behind them and finally get their season off and running.
But following Birmingham's performance, that may be a lot tougher as opponents will know that by creating pressure early on, they may be able to stop the fans having a positive influence on the game.
