Super-rich City have been credited with an interest in the Ivory Coast midfield giant, while Arsenal, for whom Toure's brother Kolo currently plays, have also been mentioned as a potential destination for the Nou Camp favourite.
Toure's agent, Dimitri Seluk, has said he has heard nothing from Eastlands officials but that his client will not be leaving Barca in any event.
"Toure is happy at Barca, currently the best team in Europe and he has no intention of moving," Seluk was quoted as telling Catalan radio station RKB.
"He is one of the best in the world in his position and it's normal that some clubs are interested in him. Manchester City have ambition and money but they have not spoken with me, they need to do it with Barca."
