Manchester United legend Roy Keane has named his best career XI.

Keane concedes he's left out several favourites from his time with United.

He explained, "Having a great career doesn't mean you are a great player - there's a big difference.

"I'm not saying Giggsy wasn't (great), but do I leave out Ronaldo, one of the world's great players? Do I leave Becks out?"

Keane's XI features several players who were swiftly sold after they challenged Sir Alex Ferguson's authority.

He continued: "You don't win titles by having choirboys in your dressing room.

"Did Beckham challenge the manager? And it doesn't mean you are challenging the manager if you marry a certain woman - far from it."

In case you were wondering, Paul Parker is preferred to Neville at right-back.

Keane's all-time Manchester United XI : Peter Schmeichel; Paul Parker, Jaap Stam, Gary Pallister, Denis Irwin; Paul Ince, Roy Keane, David Beckham, Eric Cantona, Cristiano Ronaldo, Ruud van Nistelrooy.
