As a player, manager and pundit, Roy Keane was, and still is, the epitome of no-nonsense. The Manchester United legend was never afraid to speak his mind during his playing career, and has remained the same when covering matches for a variety of broadcasters in recent years. If Keane doesn't like something, you'll certainly know about it.
Given that Keane came up against Liverpool on 26 occasions as a player his dislike for them was understandable. The two clubs, for several years at least, were competing at the top end of the division - there was simply no room for friendship or niceties, not that there every would have been any between English football's greatest rivals.
In 2005, just before Keane had been replaced as captain by Gary Neville, the competition between Liverpool and United was still prominent. So, when Peter Crouch - who had signed for the Merseyside club from Southampton that summer - attempted to speak to Keane at a set of traffic lights, the conversation was lacking.
