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.”
Yaya, younger brother of Arsenal defender Kolo Toure, earns £2.4million a year at the Nou Camp.
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.
