Paul Caddis has been told to find himself a new club this month by boss Gianfranco Zola, according to BBC Sport.
The experienced defender has been with the Blues since 2013, but has been largely frozen out of the Championship side’s first-team plans, and has failed to make a league appearance this season.
However, manager Zola told BBC Sport that if the Scotland international would prefer to stay and fight for his place than to leave the club, then he is willing to give him a chance to prove himself.
“We have had a very good chat. I’ve told him very clearly that I don’t mind if he wants to stay.
“He has players in front of him in his position, but I’ve told him that if you want to stay and fight and you deserve to play, then you will play.”
Caddis moved to St Andrew’s from Swindon Town in 2013, and established himself as a favourite among the Blues faithful.
His finest moment in a Birmingham shirt came on the final day of the 2013/14 season, when he headed home a 93rd-minute equaliser at Bolton Wanderers to keep his side from relegation to the third tier for the first time since the mid-1990s.
And last year he made his debut for the Scotland national team against the Czech Republic, coming on as a late substitute in a 1-0 victory.
At 28 years of age, Caddis still has plenty to offer to any potential suitors, with his versatility on the pitch perhaps his most valuable asset; he is comfortable in a number of positions across the back four and midfield.
