Charlton and Crystal Palace have so far been unable to agree a deal for Sullay Kaikai to move to The Valley on loan.
The Addicks are keen for winger Kaikai, 22, to join them for the rest of the season and were previously hopeful of a deal.
However, talks between the two clubs appear to have reached a stalemate and Charlton are considering potential back-up options as they look to add to their squad.
Kaikai, whose only league appearance for Palace this season came last August, is keen to make the move and he is Charlton’s number one target ahead of the transfer deadline.
Discussions are continuing, with Charlton still hoping an agreement can be reached.
Brentford, where he was previously on loan, recently made an enquiry with a view to signing him on a permanent basis, but the Bees did not follow up their interest.
The Southwark-born Kaikai made 18 appearances for Brentford during his loan spell at Griffin Park last season, scoring three goals. Twelve of those outings came as a substitute.
He has made a total nine first-team appearances for Palace, with only six coming in the league.
