Brentford defender Karleigh Osborne is reportedly attracting interest from other clubs after failing to agree new terms on a deal at Griffin Park.
The 23 year-old came through the Bees Apprenticeship programme in 2006 and has gone on to make over 150 appearances for the League One club since making his debut as a 17 year-old.
Brentford turned down bids from Charlton for the player in the summer but may be forced to sell him in the January transfer window if no new deal can be brokered.
Charlton who are still thought to be interested in the player will face competition from an unknown Championship club for his signature.
