Nowt wrong with your memory! I watched that on telly and can't recall the ref being a woman. Nicole Petignat was her name.When we went to the Faroe lslands to play Streymur 2008 ish, top place, top trip and top result. I am sure we had a female referee, 12 years on and surprised we don't see it more on a regular basis.
This is the match sheet of the UEFA-Cup Qualifikation game between EB/Streymur and Manchester City on Jul 17, 2008.
