Sir Alex Ferguson: "He is a natural goalscorer and his record is fantastic.
"He is 29 now and he has just got to stay the way he has been for 10 years.
"His injuries have always been the main subject and that is probably why everyone in Europe was not after him.
"We don't think we have taken a risk, given his record as a goalscorer.
"It is a good punt, or a good bet on him to do well, and hopefully we are right.
"Ronaldo is fantastic - the best player in the world - and we wish him well.
"He has given us six great years and it is difficult to hold onto players from other countries for that long.
"We were lucky. I never expected to have him for more than six years.
"The move to Madrid was something he wanted and we thought we should grant him that. He was great for us, never let us down and was a great professional.
"He will do well next year."
