I think he's got everything it takes but at Benfica it's very easy to shine and look like a superior class player these days. Any player will look good playing for us, specially domestically.
(Look at what happened to our defence this summer... it's almost all gone. Only Grimaldo left and being a La Masia product he won't stay for long here.)
This is relevant because by watching him during last season, I wouldn't hold back in saying that he's one of the top 5 right backs in Europe, but after watching him play for the NT, I'm not sure he can perform at his best level for any side. He looked nervous and out of his depth in the confed cup and even before that, unlike for Benfica where he looked 10x the player.
But like I said, he's got everything: pace, dribble, passing ability and defensive awareness. It would be great to see him do well.
I know anyone can look world class on youtube but this is a good sample of what he can do
