He was always going to be a centre back even at Barnsley, he just started out a right back when he first broke into the first team so any mistakes he made wouldn't be as costly as they would at centre back, as a 18 year old he needed protection until he'd gained experience that's all, once his confidence had grown he was always going to move over. We're doing the same now with a young kid called Mason Holgate he's only 18 with a hand full of first team games to his name, he's always been a centre back in the under 18s but his first team appearances have been at right back, until yesterday when he played central once our centre back got injured and was superb, he'll do the same as what Stones did he'll leave for a premier league club and be classed as a right back but really he's always going to be a world class centre back.
