It wasn't misjudged by that much, he was only an inch or two away from getting a touch. And I suspect that even if he'd turned and started running as the pass was played he wasn't getting anywhere near the man before the ball hit the net. But, aye, that in itself is indicative that perhaps his positioning wasn't ideal in the first place.
Sometimes, also, you just need to take your hat off to the opposition - that pass from Shaughnessy was perfect.
