All of the mentioned + Harry Bunn, about the only Mancunian who stands even the slightest chance in the next few years.
But like Mourinho, Mancini prefers to buy than persist with youth products so I'm not sure even the exceptionally talented will get much of a chance (at least not until the pressure is off Mancini, if ever). Razak has the best chance as he plays a role we aren't massively overstocked with. Assulin/Roman/Suarez have their work cut out for them now with Nasri and Silva at the club although the latter two are still teenagers so lots of time.
