I was at a game about that time when Martin had 3 penalties, I thought he scored all 3 and re-took one that was saved, as the keeper moved. Tried to google it but I think it must have been this game and my memory playing tricks.I remember a game v Crystal Palace in 69 where Neil Martin scored 2 pens for us but I recall John Jackson saving at least on penalty.
I was there for that. It was a league cup match. Lost 3-1. Ours was a cracker from Benno.I recall Jan Molby scored a hat trick, all penalties, for Liverpool, against us in the 1980's.
