Charlton, Brentford and Brighton are all fighting for the signature of Stevenage Borough defender Michael Bostwick, skysports.com understands.
Bostwick was named the club's player of the season last term after a number of assured displays in their backline.
Stevenage conceded just 24 goals in 44 Blue Square Premier League games as they romped to the title with an impressive haul of 99 points.
The 22-year-old's impressive form alerted a number of sides, with the League One trio now in the race for his signature.
Bostwick started his career as a trainee with Millwall before joining Rushden & Diamonds, Ebbsfleet and then Stevenage.
