Rowett left his job at Burton Albion to take the vacant managers seat at St Andrew’s Stadium, arriving at the club in the wake of last Saturday’s 8-0 defeat to Bournemouth.
Outgoing boss Lee Clark had a less than impressive stay with the Blues, scraping to survival in the Championship last season with an injury time equaliser on the final day of the season, and Birmingham bosses will be keen to see Rowett - who had been approached by fellow Championship side Blackpool earlier this term - restore the club to their recent Premier League standing.
The 40-year-old spent a two-year spell with the Blues as a player, signing in 1998 and going on to make 86 league appearances before departing for Leicester and then Charlton. Having ended his playing career with Burton in 2007, he was appointed full-time manager in May 2012 and he leaves the club with a win ratio of 44.4% in 142 games.
He takes charge of his first game this weekend, with the 23rd-placed club traveling to high-flying Wolves in an attempt to move out of the relegation places, and Wolves head coach Kenny Jackett is delighted to see Rowett make the step up into the Championship.
Speaking to the official Wolves website, Jackett said: “Gary has done very well at Burton over a number of seasons and quite rightly gets the chance now at Championship level.
“I am sure their club will respond positively to a new manager after that defeat [8-0 to Bournemouth].
“He is an ex-Birmingham player and I am sure he will lift and re-focus the whole club.”
A win for the Blues would be just their third of the season, and it could see them move onto 14 points and out of the relegation places. However, Wolves will be doing all they can to take advantage of the competitiveness at the top of the table, with a win able to move them three points clear into first place, dependant on results elsewhere.
