Portugal coach Carlos Queiroz says the work ethic of
Real Madrid star
Cristiano Ronaldo comes from his
former Manchester United
teammates.
He told the Daily Mail: "I think he learned at
Manchester United from players
like Roy Keane, Paul Scholes and Ryan
Giggs, because they all had that winning mentality
and a determination to work hard.
"With Cristiano's nature in that environment, he grew up
overnight. It was a factory like no other in football."
