Portsmouth have rejected Lens' offer of being able to play on loan striker Aruna Dindane in the FA Cup final against Chelsea on May 15.
The French outfit have agreed to waive a £4million payment clause in his contract that is due if he plays another game for the south coast side but Pompey officials had hoped he could play in their Premier League games leading up to their cup final appearance against Chelsea.
However, it appears that a decision has not been reached between the two parties and the Ivory Coast star looks like he could miss the showpiece tie.
Speaking to reporters, club administrator Andrew Andronikou said:"The club (Lens) have now agreed to let him play in the final because they think it would be a good platform for him to get a move.
"But Portsmouth's feeling is that he needs to play in the other games leading up to the final and he needs to be totally match-fit to play against Chelsea.
"I have made a last-ditch attempt to find some rational ground between us. We told Lens that this is our stance, and basically it is a take-it-or-leave-it offer from us.
"We will see what happens over the weekend, but I have so much to do and many more issues to look after that I can't afford much more time on this one."
