2. Adrian Mariappa
The 29-year-old became a free agent at the end of last season when his three-year stay with Crystal Palace came to an end.
The Jamaica international only made 49 appearances during his time with the club, following successful spells with both Watford and Reading.
The central defender, who is also more than capable playing at full-back, is captain of his national team and has made 38 appearances for the Reggae Boyz.
Rumours suggest that Hull City may be interested in signing the defender and Mariappa would certainly like to be given another chance to prove himself at the top level.
