I'll never forget Roy Essandoh's miss for Motherwell against Ipswich in Colin O'Neill's testimonial.
A long, mazy, powerful, skillful run in which he passed players like they weren't there against a side who had a few decent players in their ranks. As the run is reaching its crescendo, with what could be one of the greatest goals ever seen at Fir Park, he calmly skinned the experienced Canadian International 'keeper Craig Forrest, took the ball in towards the empty net for a few more touches then proceeded to miss an open goal from about 3 yards.
