ROY KEANE played alongside some of Manchester United's all-time great players but the Irishman claims just five were world class and Cristiano Ronaldo was not one of them.
Keano was a TV pundit for United's 1-1 home draw with Arsenal on Monday and made the stunning revelation after the game.
1 Roy Keane says Denis Irwin was world class but left Cristiano Ronaldo off his list
The Irishman captained United during a historically successful period for the club and won the Premier League seven times with the Red Devils.
Jamie Carragher posed the question to the 48-year-old in the Sky Sports studio and Keane's answer surprised fans watching at home.
He said: "We never gave ourselves an opportunity to talk about players being world class.
"But if I look back now, you'd have to class Giggsy.
"I always class the world-class players as lads who were doing it for nine, 10, 11 years – obviously Giggsy's done it for a lot longer but to me, that's the key to being a really good player: you've got to be consistent.
"We see players now, they have a good month and patting themselves on the back.
"You have to be good for years and years, and Giggsy would have been a prime example."
