Two of the fiercest competitors in Premier League history have come face-to-face for a new documentary exploring their heated rivalry, to be shown on ITV 4 next week.
Former Manchester United captain Roy Keane and ex-Arsenal skipper Patrick Vieira went in front of the cameras to discuss what drove them during nearly a decade of clashes on and off the pitch, with the result to feature in a programme titled 'Best of Enemies.'
The midfield generals were involved in a string of infamous showdowns, which included a bust-up in the tunnel at Highbury before a Premier League clash in 2005.
Keane intervened and confronted Vieira after he exchanged angry words with Gary Neville, with their feud coming close to boiling point before a ball had even been kicked that evening.
That exchange was just the tip of the iceberg in a contest which included Vieira taking a swipe at Keane in 1999, before a mass brawl involving both sides at Old Trafford in 2003, in a match in which the Frenchman received a red card.
A 30-second teaser for the show features intense snippets from both men, with Keane kicking things off with: "Hatred was the right word. I don't think he was as tough as me.
Vieira responds with: "He wasn't frightening at all."
