Not the best team, but one of the best performances i've seen at the County Ground was Derby in December 92. They played us off the park that day, were 3 up after 87 minutes, ended 4-2 with Maskell also missing a penalty at the end but they were all over us and the scoreline was totally misleading, they should have won by 4 or 5 clear goals.
However, although their away form was excellent, their home form wasn't and they ended up finishing halfway whilst we went up.
I remember that game, I was in the derby end with a derby supporting mate. Absolute torture. I thought it was 5-2 though.
