Sky Sports understands Crystal Palace defender Kadell Daniel has turned down a new deal at Selhurst Park.
Daniel's current deal expires at the end of the season and he has opted against taking up the option of extending it for a further year.
The news has alerted a number of clubs to Daniel's possible availability this summer on a free transfer when his contract expires.
A host of League One, League Two and SPL sides are all thought to be keeping a watching brief on the full-back, who can also play in midfield.
The 18-year-old, who has come through the ranks at Palace, has yet to make a first-team appearance for the Eagles.
