Roy Keane has reignited his feud with former Manchester United manager Sir Alex Ferguson.

Both have been critical of each other since Keane's legendary career at United finished in 2005.

And Keane says he would never forgive the Scotsman.

"I wouldn't forgive Ferguson. The media spin, how I apparently upset everybody, it was all nonsense," Keane told Off The Ball.

"I don't care if it's Alex Ferguson or the Pope, you're going to defend yourself.

"People talk about Ferguson's man-management. Nonsense. People said he always had the best interests of Manchester United at heart. Darren Ferguson [his son] won a medal. He was very lucky."
