Ailton has accepted the offer to play for Qatar and will be paid over $1 million per season.
Fellow Brazilian Dede and his brother Leandro are also thinking over switching their international allegiances, and Qatar have made yet more offers.
Werder Bremen's French defender Valerien Ismael is reported to have shunned Qatar's offer, but they are believed to have made further approaches.
Bordeaux's Jean-Claude Darcheville, Yann Lachuer of Auxerre, Nantes' Stephane Ziani and Frederic Piquionne (pictured) of Rennes are all thought to be considering offers.
