Town are again among a number of clubs being linked with Northampton keeper David Cornell, who is out of contract at the end of the season.
According to Football Insider, the Blues, Derby County and Blackburn Rovers are all considering late moves for the 28-year-old, who was previously mentioned in connection with Town at the start of December.
Born in Waunarlwydd in Wales, Cornell started his career at Swansea during which time he had spells on loan at Port Talbot, Hereford, St Mirren and Portsmouth before moving on to Oldham in the summer of July 2015 having made only one League Cup appearance for the Swans.
In June 2016 he joined Northampton and has made 99 starts and one sub appearance for League Two’s sixth-placed side.
Cornell, who is 6ft 2in tall, could be set for a first senior Wales call-up, having been capped at U17, U19 and U21 levels, given his form this season.
Despite Bartosz Bialkowski’s departure for Millwall on a permanent basis earlier today, the Blues don’t appear in immediate need of another keeper.
Summer signing Tomas Holy is currently deputy to on-loan Wolves man Will Norris, who said last week that he expects to stay with the Blues for the rest of the season.
Town also gave a first senior appearance to current Wales U21 international Adam Przybek in the Leasing.com Trophy earlier in the season, while Harry Wright, son of ex-Blues keeper Richard, might also have made his debut but for injury.
