Town are reported to be among the clubs eyeing former Sunderland midfielder Ethan Robson.
Previously it was reported that Portsmouth, Oxford and unnamed Scottish Premiership sides were vying for the 23-year-old’s signature following his release by the Black Cats, however, according to the Portsmouth News, the Blues, Fleetwood and Blackpool are also interested.
Houghton-le-Spring-born Robson came through the youth system at Sunderland and made nine starts and five sub appearances for the Wearsiders, scoring once, prior to spending loan spells at Dundee and Grimsby in the last two seasons.
Robson is primarily a central midfield player and it would be a big surprise if the Blues were looking for a further signing in that area of the field with manager Paul Lambert already having plenty of options.
