3) Arturo Vidal (Juventus)
The Chilean World Cup star rejected interest from Manchester United during the summer transfer window, but could he be tempted away if City come knocking? He certainly has the workmanlike abilities to contribute to both attack and defensive elements of play, which is something Toure has done so wonderfully over the years for City. There are concerns over some long-term injury issues for the 27-year-old, and any potential suitor would have to be certain before making their move.
