MADRID - Diego Forlan and Sergio Aguero's names are being used by other clubs as leverage tools in their transfer dealings, Atletico Madrid president Enrique Cerezo said on Monday. Atletico's Uruguayan and Argentine strikers have been linked in the media with moves to Real Madrid, Barcelona and Chelsea among others, as the battle for the signature of Valencia forward David Villa intensifies. "No club or representative has been in touch. We don't have offers for our players ... we don't want to sell," Cerezo told the club's website. "I think our club could be being used to help close other transfer operations."
