Chelsea faces Liverpool in the Carabao Cup final, and although the two teams are not traditional rivals, there is a sense of bad blood between the fans.
It's difficult to pinpoint exactly where this rivalry arose from. Did it develop recently regarding Liverpool's recent rise in success, or is it because we took their star striker in 2010, Fernando Torres? Could it also be from their main man Steven Gerrard handing in a transfer request because he wanted a move to west London?
There are several chapters in history to choose from. However, the arrival of Jose Mourinho and Rafa Benitez in 2004 may have been the main catalyst.
