BOLTON have made an enquiry for Millwall midfielder Liam Trotter.
Trotter has been a long-term target for boss Dougie Freedman and the Lions' Championship rivals are trying to agree a deal for the 25-year-old before Friday's transfer deadline.
It is understood the two clubs are some way apart in their valuation of the former Ipswich Town trainee, who is out-of-contract in the summer.
Freedman made an approach for Trotter in December 2012, and was also eager to sign him when he was Crystal Palace manager.
A source confirmed that negotiations would go "right down to the wire", with the window closing at 11pm tomorrow.
Millwall offered Trotter a new, double-your-money deal before Christmas but he has so far been reluctant to discuss an extension – albeit under ex-manager Steve Lomas.
Ian Holloway has threatened to sell players who refuse to commit their futures to the club.
If Trotter goes, the Lions could turn to Yeovil Town star Ed Upson to replace him.
