God yeah, hard to believe somebody forged a professional career as a left winger and failed to spot that simple pass. I'll comfort myself with the assumption that we would probably still have lost (compared to, say, Ray Houghton at Wembley).
Edit- Ha! Hadn't actually seen OwlFan's post.
On a similar note, McClean's chance to make it 2-0 against Denmark could have seriously altered the course of history also.
