Paul Groves has agreed a new contract which will see him extend his stay on as assistant coach at Birmingham for a further season.
Groves has signed a 12-month rolling deal and will continue to assist Blues boss Harry Redknapp.
Redknapp, who was confirmed as City’s permanent manager last week, initially brought in Groves on a short-term basis after agreeing to take charge of the club’s final three games of the season.
The pair, along with fellow coach Steve Cotterill, guided Blues to two victories from the three matches as they avoided relegation on the final day.
News of Groves’ contract extension, announced on Birmingham’s official website, comes a day after Cotterill turned down the assistant manager’s role and left St Andrew’s.
