Town have held talks with former Manchester United keeper Roy Carroll, according to one of Sunday's tabloids. The 32-year-old, who is currently with Odense BK in Denmark, played alongside Blues boss Roy Keane at Old Trafford.
Keane is said to be ready to offer Carroll the chance to return to the UK, the 19-times capped Northern Irish international having been named the 2009 Goalkeeper of the Year in Denmark.
Enniskillen-born Carroll started his career with Hull City, subsequently moving on to Wigan Athletic, Manchester United, West Ham United, Rangers and Derby County prior to signing a three-year deal with Odense last summer.
Town are certainly on the lookout for another keeper with Keane having said he likes to have three glovesmen on the books on a number of occasions.
On Friday, Sunderland boss Steve Bruce confirmed that the Blues had made an enquiry regarding Márton Fülöp after reports that Town had tabled a £1 million bid for the Hungarian international.
