Southampton defender Aaron Martin has reportedly been made available by his club this summer.
The 23-year-old, who joined the Saints from Eastleigh in 2009, has made 22 first-team appearances for the Premier League club so far.
According to Sky Sports News, the defender is not part of manager Mauricio Pochettino's plans for the new season, with a number of clubs monitoring proceedings.
Martin spent spells on loan with Coventry City and Crystal Palace last season.
