Town are reported to be showing interest in out-of-contract Yeovil pair Byron Webster and Luke Ayling.
The Glovers, whose relegation back to League One was confirmed last week, are keen to keep hold of the central defender and right-back and manager Gary Johnson has already held talks with the duo and his other out of contract players, but is not yet sure of his budget for 2014/15.
According to the Western Gazette the Blues and Leeds are eyeing 27-year-old Webster, while newly-promoted Brentford and Town have kept tabs on 22-year-old Ayling.
Yorkshireman Webster (pictured above) was with Leeds as a youngster before moving on to York, where he broke into the first team during 2004/05 when the Minstermen were in the Conference.
The 6ft 3in tall defender subsequently spent time playing with Harrogate, Whitby, Czech side FK SIAD Most, Doncaster, Hereford and Northampton before joining Yeovil, where he is currently vice-captain, in 2012. He has now made 94 starts and three sub appearances for the Somerset club, scoring nine goals.
Londoner Ayling was an academy player with Arsenal and joined the Glovers on loan in March 2010 before signing a permanent deal during the following close season. He has made 172 starts and 12 sub appearances for the Glovers, scoring three goals.
As well as being able to operate across the defence, Ayling, who would be subject to a compensation payment should he move on this summer, can play in midfield.
