You could look at shots missed and unsuccessful dribbles, but that doesn't take into account whether that shot was missed because he hit a screamer and missed from a couple of inches, or skied it 50 feet high because he tripped. Same for dribbling; was he outpaced or out muscled to the ball, or did he trip? He is brilliant outside of the box for control and in his stride, I give you that. But when he gets into the box and has to take more than one touch, his feet turn to mush. His most effective technique when on goal is hit it first time, just like he did with his two goals. If he takes any more than one touch, he overthinks and loses the ball more often than not. Surely you have noticed this on more than one occasion?
