Birmingham are set to offer Steven Carr a new contract as they prepare for life in the Premier League.
The Blues will be plying their trade in the top flight next term after finishing as runners-up behind Wolves in the Championship.
Alex McLeish is now looking to piece together a squad capable of competing among England's elite and sees Carr as crucial to those plans.
The 32-year-old's career appeared to be over when he announced his retirement from the game in December.
However, he was coaxed back into the professional ranks by McLeish in February as the Blues looked to find experienced cover at full-back.
Carr went on to make such an impression that his short-term deal was extended until the end of the season.
Birmingham are now keen to tie him down for the foreseeable future, with the former Newcastle and Tottenham man close to penning a permanent contract.
McLeish said: "Stephen Carr has been excellent for us.
"The quality he has shown from his experience at Spurs and Newcastle and the Republic of Ireland has been superb.
"He has brought a lot to the team. He came out of retirement and was a real find for us."
McLeish is also keen to keep Lee Bowyer at St Andrews, with last season's loan star set to be out of contract at West Ham over the summer.
