The Sun says City have made a stunning £24million bid for Barcelona midfield star Toure.
Barca will fight tooth and nail to keep Toure.
A top source at the club said: "There is an offer for Yaya but the club will do what is necessary to convince the player to stay."
It is understood City will DOUBLE his wages in an effort to tempt him away.
Toure scored a sensational solo goal in the 3-1 win over Real Mallorca last weekend.
