They probably didn't regret it in the end. My unbiased memory is that we dominated throughout, played the better football, couldn't score (is this sounding familiar?), they were supposedly the superior team, but that day they played hoofball, and roughed us up. Unfortunately they scored a couple of decent goals in the first half, and that was that. The fact that Derek Dougan scored 2 goals to knock them out in the semi-final meant he became an instant hero. But I don't think I've ever looked forward to derby matches since.
