Atletico Madrid president Enrique Cerezo has revealed he would have to receive an offer of at least €60 million to tempt him to sell Argentine sensation Sergio Aguero, although that may not even be enough. The 21-year-old, who has netted 42 league goals in 112 appearances for the rojiblancos since arriving from Independiente in 2006, had been linked with moves to Chelsea and Inter Milan earlier this summer. Later reports suggested Premier League champions Manchester United were keen on acquiring the Argentina international's services as they attempt to find a replacement for Real Madrid-bound FIFA World Player of the Year Cristiano Ronaldo. While the Red Devils' North West rivals Liverpool are believed to be interested in the front-man, along with Valencia goal-getter David Villa, as they seek support for talisman Fernando Torres. However, the Vicente Calderon outfit have already had to deal with transfer speculation linking their other goal-machine, Diego Forlan, with a move away from the club in recent months. And club president Cerezo has insisted it would take a monster bid for him to even consider the possibility of parting company with Aguero. "Perhaps even if an offer for this amount [€60 million] of money arrives, we would not accept the sale," he told the Spanish media.
