Personally, for me it was Celtic eliminating Barcelona from the UEFA Cup, at a time when they were on fire. Then just a couple of days later travelling to Ibrox for 'Sombrero Sunday II' and beating them also. I was in Florida and watched both games at strange times, but so happy nevertheless.
I remember that game Milanista, 2 awesome second-half long rangers from Kaka and Seedorf, fantastic match. Although Deportivo thumping Milan was also very exciting.
England France then Portugal England were both fantastic to watch, the first for the hilarity of England being 'cruelly' gubbed in minutes and the second for a superbly entertaining game, and for England again being gubbed :mrgreen:.
