Luton Town are leading the chase to land Republic of Ireland defender Marc Wilson.
The 31-year-old is a free agent after spending last term with Bolton, but he left after they were relegated to League One.
A number of Championship clubs have been in talks with Wilson – who can also play in midfield – but the former Sunderland, Bournemouth and Portsmouth man looks set for a move to Kenilworth Road.
Wilson spent a brief period of time on loan at Luton in his formative years, when Pompey sent him there for experience in 2007, when he was aged 20.
That spell did not last long, as the club soon went into administration, but Wilson is now closing in on a permanent return, more than a decade on.
