mine is the QF UEFA Cup 2002. Feyenoord played PSV at home after a 1-1 draw in Eindhoven. It's the 89th minute and PSV is 0-1 in front as Pierre van Hooijdonk scores a miracle header....I was in the stadium just behind the goal and I never felt such a hugh explosion of emotion in all my life (at least at a soccer game). The rest is history...FEYENOORD kicked PSV out of the Cup after PK's and later became UEFA CUP winner 2002 in their own stadium 'De Kuip' in Rotterdam.
those were the days....
