Montpellier chairman Louis Nicollin would love to bring Andre-Pierre Gignac to the club, but claims his wages would scupper any deal.
Having moved to the top of the Ligue 1 standings, Montpellier are expected to add during the January transfer window.
Fresh faces will be important if they are to maintain their current form and spring a surprise by landing the French title.
Marseille striker Gignac has been mentioned as a possible target, with the France international having endured a troubled time at Stade Velodrome.
Nicollin would be happy to take the 25-year-old forward, but says Montpellier do not have the funds to finance a transfer.
"If he came to Montpellier, within six months he would be a France international again," he told L'Equipe.
"He is an emotional player and he needs a club like ours. But considering his wages, it would be impossible."
Meanwhile, Nicollin has revealed plans to keep highly-rated midfielder Younes Belhanda at Montpellier for one more season.
He said: "PSG's interest in Belhanda? If they pay €40million (£34m) I will put him on a plane to Paris.
"He is a good guy and he should remain here for one more year because he still has things to work on.
"No player has expressed a desire to leave."
