True. But I can see many City fans getting very frustrated if Stones makes a few mistakes, which will happen because he's a young CB with a load of pressure on him who's playing a difficult and risky, if effective, style. There's always a risk that a defensive mistake will cost a team in the long run like Lescott's mistake almost cost us the PL title, regardless of how good the player is, they will make mistakes. Most City fans, including me, will be patient. Not everyone will feel the same.You may see it as an optional bonus but the man in charge sees it as vital.
