Town are reported to be keeping tabs on Dundee United central defender Gavin Gunning.
According to the Dundee Evening Telegraph, the 23-year-old, who was previously linked with the Blues in the summer of 2012, is also believed to be interesting Italian side Palermo, as well as Rangers and Celtic, with his contract at Tannadice up in the summer.
Dubliner Gunning played youth football with St Joseph’s Boys Club and Crumlin United before moving to England and joining the Blackburn Rovers academy in 2006.
The 6ft 2in tall centre-half or left-back subsequently went out on loan to Tranmere, Rotherham, Bury and Motherwell but failed to make a senior appearance for the Ewood Park club.
The former Republic of Ireland U21 international signed for Dundee United in the summer of 2012, turning down Aberdeen, former loan side Motherwell and Scunthorpe, and since moving to Tannidice he has made 83 starts and three sub appearances, scoring 10 goals.
