Millwall are reported to be leading the chase to sign former Blues midfielder Lee Martin. The 26-year-old left Portman Road at the end of the season.
A number of other clubs are said to be interested in the one-time Manchester United man, who spent four years with the Blues.
Town offered Martin vastly reduced terms in May but the winger opted to move on and look for a new club.
Joining Millwall - who are at Portman Road on the second weekend of the new season - might suit Martin, who was brought up not far away in Bromley.
