Most of those clips were play from RB, not I put much weight in what's on a YouTube compilation, with some good passes, different to an attacking midfielder.watched a lot of highlights reels of his and its easy to tell he is very attack minded and already has that vision and range of passing. for example :
and he was a very very young then
Playing at CB, as he did for most of last season, won't have stunted his growth. It will have helped him improve the defensive side of his game, get a lot more time than he would've otherwise and get used to the pace of the premier league. He is way ahead of where it would've been planned for when he joined.
