Liverpool 3-3 AC Milan, Champions League Final 2005
The greatest comeback ever, do we really need to remind anyone about this? Liverpool were the underdogs in this game against an AC Milan side that featured Maldini, Crespo, Shevchenko, Inzaghi, Gattuso, Seedorf, Cafu and a host of others. Liverpool had Djimi Traore.
The Reds trailed 3-0 at halftime but Rafa Benitez and Steven Gerrard turned on the magic in the second half and six minutes of madness got the score at 3-3. Liverpool battled hard and ensured they went into the penalty shootout which they won. Easily the greatest comeback in the history of the UEFA Champions League.
