We did Chester and Colchester both 6-0 very close together in about 73/74It was our biggest-ever victory in the top division, I think they said. Which is true. Our biggest win in the old first division was 4-1 v Man City, which we've bettered with 4-0s v Manchester United and West Ham. I suppose the 5-2 v Leicester was also better, as we scored more although the margin of victory is the same.
York was 7-2, by the way, not 9-2. We also beat Charlton 7-0 in the second tier in 1983.
