CHO's versatility is what gives me hope for the lad. He can be a very productive player in the final third.
If he's on the left, he will always look to cut in, beat a player with his pace, then take a shot. If on the right, he will stay wide and provide the team some width, take a player on then put in a cross (as we saw last night)
His defensive work also shouldn't go unnoticed as well. Did a lot of the donkey work given Azpilicueta had a mare last night.
