We have just lost a potentially world class CB in John Stones. I am not too upset really because if we get Williams then we have instantly strengthened our defence. Williams is a better defender than Stones as are a few CBs in the league. Its Stones footballing skills that stand out from the rest nothing else. Short term we will be much stronger but if and only if Stones continues to progress he will be one of the best CBs the premier league will have produced. Risky going to City because a couple of high profile mistakes there will be jumped on harder than it ever has been at Everton and he may find himself frozen out if he doesn't get a consistency. I wish him luck but will miss his arrogance and silky skills but not his defensive frailties.
