Town, Nottingham Forest and Norwich City are chasing Birmingham City midfielder Keith Fahey, according to reports in Ireland. Elsewhere, the Blues are also linked with Watford's Jonathan Hogg and Manchester United’s Nick Powell.
Irish international Fahey, 29, was with Arsenal’s academy and moved on to Aston Villa while still a youth player, but failed to make a first team appearance and returned to Ireland.
The Dubliner, who has been capped 16 times by his country, scoring three goals, played for Bluebell United, St Patrick’s Athletic and Drogheda before joining Birmingham in January 2009.
Since then he has made 107 starts and 35 sub appearances for the Midlanders, scoring nine times.
Fahey, who is out of contract at the end of the season, has been back in Ireland on compassionate leave for the last seven weeks.
Forest are now managed by Alex McLeish and Norwich by Chris Hughton, both of whom were previously in charge at Birmingham.
Meanwhile, the Blues are being linked with a permanent move for 24-year-old Watford defensive midfielder Jonathan Hogg.
The £1 million-rated Teessider also learnt his trade at Aston Villa, spending time on loan at Darlington and Portsmouth while at Villa Park.
Having made seven appearances for the Premier League club Hogg moved on to Watford in the summer of 2011 for an undisclosed fee, signing a three-year contract.
Hogg has been a regular in the increasingly impressive Watford side this season but reportedly could become a victim of Gianfranco Zola's revolution at Vicarage Road,
Elsewhere, Town, Leicester and Peterborough are all claimed to be interested in signing Manchester United midfielder Nick Powell on loan for the rest of the season.
The 18-year-old was previously a Blues target during his time with Crewe Alexandra.
