Leverkusen 01/02 - why oh why we took Hamann off I'll never understand. We would have beaten United in the semi's. Probably not Madrid in the final but it would have still put us right at the forefront of European football again. Was downhill from there under Houllier.
Pretty much every time we got knocked out of Europe under Rafa. Benfica, Milan, Chelsea x2, Atletico.. Always felt hard done by and always felt as though we would have gone on to win the trophy had we progressed.
