He had a moment just before the Stones blunder where he was easily deprived of a ball that should have been his and Virge had to mop things up, and there were a few other occasions where he was gotten the better of physically when the ball was there to win.
For the benefit of those who have become defensive and aren't seeing the wood for the trees, I'm sure that those who have been talking him up have seen a great player in him, and that age of being only 19 means they attach special status to him. I have only watched him twice, but in those 2 games I have seen more blunders leading to goals than I have seen from any of our CBs this entire season. Maybe I'm his Kryptonite and I have witnessed his only abominations, but I can only say that I believe he needs to develop before he is ready for the very highest level.
