Mark Pembridge volley for Luton 1991. If memory serves it was like McGinn"s vs Sheffield Wed last season.
Only 1 contender for me - Johan Cruyff for Barcelona at Villa Park in the EUFA Cup on 1st March 1978. Barca's 1st goal on the night when he glided from the half way line past numerous Villa players and from just outside the penalty area hit it into the bottom corner. I was on the Holte End directly in line with him when he shot and immediately could see it was never going to be saved. That was the one and only time that I have ever seen an opposition player getting a standing ovation from the Villa crowd.
