Don't confuse England starting places, with what someone is supposedly worth!
Stones pisses on Smalling and Cahill. He is paying the price for being poorly managed/coached at Everton last season. Sure he made mistakes too, that can't be denied, but the lad is class in my opinion.
It's very telling when you have arguably 2 of the best managers in world football in Pep and Mourinho, who both have completely differing styles and ideas on how a team should set-up, yet both of these really want Stones.
For me the only test Stones has to pass is the mentality test. An English signing for a huge fee always attracts attention and its how he copes withy it all, he'll make mistakes, like every player, but if he thought he was under the spotlight this season just gone, just wait til he signs for us for £40mil +.
For what it's worth, with his talent playing under Pep, I think he'll blow everyone away.
