he was barged off the ball in a coming together - while it was a definite penalty - I have seen many similar not given.
While the freeman one, together with the one Darren mentioned Kenny got away with against Hull, where absolutely full on stanewallers with no room for interpretation otherwise by all officials.
Another one I remember was v Millwall at the Lane on 4/2/84. We were going through a sticky patch on our promotion bid and had not won since New Year's Eve. We really needed to beat Millwall and were leading 1-0 through a Morris goal, when about 5 mins from the end, a Millwall player broke through with only Tomlinson to beat and Joe Bolton was just behind and literally grabbed him by the shoulders and wrestled him to the ground. A clear pen we all thought, but not given!
To add insult to injury, we went up the other end and Arnott scored to give us a much needed 2-0 win.
