Hibernian duo Scott Brown and Kevin Thomson have demanded showdown talks with chairman Rod Petrie over their futures.
Both players are unhappy that Hibs denied them the chance to win a move to England after they turned down a £3million bid from Charlton for the pair.
Thomson and Brown are both considering their futures at Easter Road after the club refused to discuss new improved deals for both players.
Brown, who saw a transfer request rejected last month, is now hoping to meet Petrie to discuss the situation.
"We've already made it clear we wanted to sign new contracts with Hibs and I'm disappointed Rod Petrie didn't agree to talk with us about that," Brown told the Daily Record.
"Now Charlton have come in with a great offer and he has knocked it back. I find that very hard to understand so it's time we put our cards on the table.
"We need to know exactly what Rod is looking for because there is a danger Hibs could be unreasonable here.
"When was the last time a Scottish player was sold for £3m? The only ones I can think of are Barry Ferguson and Duncan Ferguson.
"James McFadden was sold to Everton by Motherwell for £1.75m and he was already a Scottish international. So it's difficult to understand why Hibs will not accept an offer of £1.5m for each of us.
"They are not willing to give us new deals and yet they are not willing to accept that kind of money for us. It doesn't make any sense."
Brown admitted he would be interested in a move to Charlton with the Premiership club thought to be ready to make a renewed move for the two midfielders again in January.
"Of course Charlton interests me," added Brown. "Who wouldn't fancy playing in the Premiership and testing yourself against guys such as Thierry Henry?
Rangers have also been strongly linked with the pair and Brown admits he would be keen on talking to them if they firmed up their interest.
"There has been a lot of talk about Rangers but we'll just have to wait and see how serious they are," said Brown.
"I would relish the chance to talk to them but I suppose it all depends on how reasonable Mr Petrie is willing to be."
