Garry Monk was unveiled as Birmingham's new manager on Monday afternoon, having signed a three-and-a-half-year deal.
He replaces Steve Cotterill, who was sacked on Saturday following a 2-1 defeat at Nottingham Forest with the club in the Sky Bet Championship relegation zone.
Monk faces former club Middlesbrough, who sacked him in December, in his first game in charge at St Andrew's on Tuesday.
'The club is in a difficult moment but these are the types of challenges I like to look at,' he said.
