Former Hearts captain Steven Pressley has undergone a medical at Charlton, but his agent has not ruled out a move to Scottish champions Celtic.
The 33-year-old was at The Valley on Wednesday and held talks with Addicks gaffer Alan Pardew.
The players agent, Blair Morgan, told the Scotsman: "He had a medical while there but nothing should be read into that. It now comes down to two excellent offers from two clubs – one in England and one in Scotland."
The Scotland international is a free agent after leaving Hearts earlier this month following his criticism of majority shareholder Vladimir Romanov.
Pressley also claimed there was "dressing-room unrest" at the Scottish Premier League club.
Pardew, who replaced Les Reed as manager of Charlton on Christmas Eve, did, however, add a note of caution after revealing his attempt to sign Pressley.
Pardew earlier said: "There is a good chance he will be at Charlton. We are interested in bringing him here before the transfer window but I am never confident about signings until they are done. What I like about him is he is a leader. I think we have got some very good centre-halves here but he comes into a pack where we need characters and leadership and that is one thing that attracts me to him."
Rangers, Southampton, Derby and Leeds have also been linked with Pressley, who is ineligible to play for any new employer before the opening of the transfer window in January. [Mof Gimmers]
