Not sure there are any doubters in Stones. The argument is always whether the manager has developed him or ruined him. Personally, I think Martinez has treated him the right way. You have to let a naturally talented footballer express himself, rather than have so called technical ability trained into him. Stones is the most naturally talented defender of his generation, and quite possibly of many generations. He'd be much better off if everyone just let him get on with his game (including the mistakes) and ditto Martinez. Amazing how many forum dwellers are more equipped and qualified to 'manage' a player than a professional manager.
Hes a shining example of why we cant have nice things.
Hes a very talented young lad, learning his trade in the hardest league in the world, not a single piece of leeway is given to the lad, simply cos he likes to play football his own way. He lost his place due to a slight injury and hes having to wait for a chance to get back, he needs games at his age and he needs to make mistakes in order to learn, its how EVERYBODY learns and gets better.
