Still young, still learning, lets remember that he was playing non-league football before last season, he's come a very long way since then, time is on his side, despite all of this he looked very comfortable for his first match, comfortable on the ball, brilliant heading, good pace, i've seen top defenders give them penalties away in big matches, can't really criticise him for that especially on his debut, as long as he doesn't do it in competitive games. Very good debut.
