4) Manchester United 1-4 Liverpool, 2009
A rare humbling at home for United, Liverpool were superb as they toar the Red Devils apart at Old Trafford towards the end of the 2008/09 season. Cristiano Ronaldo gave the home side the lead from the spot, but goals from Fernando Torres and Steven Gerrard turned things around before half time. Late on, Fabio Aurellio and Andrea Dossena added two more to make it a surprise scoreline, though the Reds still missed out on their rivals to the Premier League title.
