Roy Keane might be a popular pundit these days, but for 15 years the Manchester United legend was a player Liverpool fans just loved to hate.
The nasty heartbeat of Sir Alex Ferguson's Premier League-dominating side, the Irishman would line up 26 times against the Reds during his career for Forest and United. A tough-tackling midfielder, he received more bookings against Liverpool (11) than any other side before hanging up his boots.
Yet Keane was far more than a hatchet man, as Liverpool legend Jamie Carragher would insist when appearing alongside the former United midfielder at a live recent edition of The Overlap on Tour.
