Not even really talking about match quality to be honest. Just a white knuckle ride for the full match. For me, its probably Arsenal vs United in the semi final replay in 1999. I dont know if I'll ever see a game like it where the momentum swung as much due to so many incidents. Second leg vs Barca in 2008 was a intense as feck as well. 1-0 with the opposition chasing an away goal was barely a lead, so that was really hard to watch. Probably more wound up watching that than the final.
