People keep referring to this as if it's just bad luck. But a shot against the woodwork is still a shot OFF target, meaning luck has nothing to do with it. The most recent one, against Burnley, was unforgivable. No more than 8 yards out with nobody closing him down and the keeper rooted to his line. He simply had to hit the target.
It's not just his poor conversion rate, it's the number of very easy chances that he fluffs completely that irks me.
