Atletico Madrid president Enrique Cerezo has told "El Partidazo de COPE" that Sergio Aguero was "stupid" to leave the club for Manchester City the way that he did.
Aguero had scored 102 goals in 233 games for Atletico, who he joined for €22 million from Independiente as a teenager, before making a €45m move to City in summer 2011.
Atletico wanted City to pay at least €60m for Aguero, and the saga dragged on for two months amid a widespread feeling that the player had tried to force through a move to crosstown rivals Real Madrid.
