I like him and his trajectory. Easy to forget given his size that he is just 17, and a fairly recent (August) one at that.
Better suitored as RB but clearly Xavi likes him if he is going to play him at LB ahead of, for example, Gerard Martin who is an actual LB and has had lower LaLiga interest.
But for a possession based RB he may end up as a first team solution as I had pointed before. And with Fresneda being a full 2 years older and not making an impact as of yet at Sporting Lisbon, we may have lucked out a little bit missing out there.
