Interesting question that Nick (I know aimed at USAF), if I may add my thoughts:
Cameo is all that was. I'd prefer to see him get 60 mins and more than one cameo to pass judgement. Remember, the kid (like Sarr and until today, Biss) has hardly had a look in and you can't impress in 10 mins. Nonetheless, I thought he tried very hard to impress, ran his arse off and some of his dribbling and movement had that Spanish swagger. Yes, seems lightweight, but imo, with experience his skillset could get him over that hurdle ala Modric.
Didn't read this before I responded...yep this!
