Very overrated player imho, and if Guardiola sees him as a long term replacement for Kompany, he needs to think again. Stones is a bit like a mediocre book with a colourful cover.
His silky ball skills when carrying the ball out of defence and dribbling around in his own penalty area allow him to flatter to deceive. He isn't that good in the air and his positional sense is often poor, plus he has often been found ball watching which has cost Everton quite a few goals. Last night in the friendly with Dynamo Dresden he gave another example of his need to develop his game when he backed off one of their players allowing him to get in a shot from the edge of the box and score a goal that looked good but a decent defender would never have allowed the shot to be made. In fairness though, as well as being calm on the ball he times his tackles very well.
His attitude stinks though and he seems to have his head stuck up his own backside. No problem with someone wanting to fulfil their potential but when Everton played hard ball with Chelsea last season his teddy came right out of his cot and he had a poor season thereafter. His ultimate shameful deed for me was while we were getting tonked by our bitter rivals at Anfield in February, he came off with "tummy ache", the poor lamb.....never seen that before and doubt I ever will again.
Can't get rid quickly enough for me, I'm just a bit worried that now we have the ability to play hardball over fees and demand top dollar for potential prospects, it might backfire with Stones and we'll end up stuck with him.
