Birmingham have appointed former West Ham assistant manager Peter Grant as first-team coach at St Andrew's.
Grant fills the role vacated by Roy Aitken, who last week left the Barclays Premier League club to link up with David O'Leary at United Arab Emirates outfit Al Ahli.
"I've known Peter for a long time. He was an adversary of mine in my Aberdeen playing days, when he was a stalwart for Celtic," Blues boss Alex McLeish told club's official website.
"He is a competitive man who has been brought up in a winner's environment due to the traditions of Celtic.
"He has successfully made the transition into becoming a coach and my diligence shows me he is the right man for the job.
"His personality is akin to that of the man we have just lost, Roy Aitken, and that will be a great asset to us."
The former Celtic, Norwich, Reading, Bournemouth and Scotland midfielder brings a wealth of coaching experience to the midlands club.
He left his player-coach post with the Cherries in 2004 to become Alan Pardew's number two at West Ham, the pair guiding the Hammers to the FA Cup final in 2006.
A 12-month spell as Norwich boss followed in 2006/7 before he became first-team coach at West Brom in summer 2008 under the management of Tony Mowbray.
He followed his former Celtic team-mate back to the Glasgow giants last summer for the ill-fated stint back at Parkhead which ended in their dismissals in March this year.
