Auxerre striker Ireneusz Jelen insists that he has a minimum fee release clause in his contract.
The Polish forward has been linked with a move from his current club to French champions Marseille, despite being under contract at Stade de l'Abbe Deschamps until 2012.
Speculation has mounted that he could sign a two-year deal with L'OM, but reports have suggested that Auxerre are denying the fact he has a €3million (£2.5m) release clause in his current deal.
He told L'Equipe: "Marseille? We are in talks for some time, and I should know more on June 10th.
"I can tell you, contrary to what Auxerre stated, I have prolonged my contract last season with a transfer clause being set at €3million.
"It exists. I am a little irritated to hear it is not true. I know what there is in my contract."
Jelen picked up a knee injury on Saturday during Poland's friendly match with Finland, but the persistent problem is not serious.
"There is nothing serious but it has disturbed me for some months," he added.
"Sometimes I had to play at Auxerre under injection to block pain."
