It comes with success.
Ex Liverpool players ruled the punditry last 20 or so years, it's Rags who are taking over now, I guess some Chelsea men will join in next few years and then it's City time :D
TVs want big names and to be honest not many of them from City are available at this moment.
But then again, not many Brittsh players around City currently. I could only see Hart being good for it. The likes of Milner or Barry doesn't look to be able to entertain anyone tbh. Eventually Lescott. Micah probably dies from laugh on funerals too, not really fit for serious TV programs.
