I have a vague memory of watching the 1966 World Cup final at friends of my grandparents.
The first game I really remember watching was the 1970 FA Cup final between Chelsea and dirty Leeds.
The first professional game I watched was an FA Cup replay at St James' Park, Exeter. The Grecians beat Leicester City 3-0, and a mate, Tony Kellow, scored all three:
The first time I saw City live was at Plymouth on 16/1/88. 2-0 up at half-time; we lost 2-3, and all the goals were scored at the other end of the ground.
My first game at Maine Road was the opening fixture of the 1990/91 season. We beat Everton 1-0, thanks to that rarest of things; an Adrian Heath goal.
