David Moyes has said that he would like to work with Cristiano Ronaldo in the future.
The Portuguese international spent six years at Manchester United before joining Real Madrid in 2009, but was linked with a return to Old Trafford in the summer, before agreeing a five-year contract extension with the Spanish side.
The United manager told MUTV: "Everyone at Manchester United would tell you he is the best in the business anyway.
"I have not been fortunate enough to work with him but there is still hope some day it might be possible."
Ronaldo's performance during Portugal's World Cup qualifier playoff against Sweden earlier this week has made him the favourite to be named this year's Ballon d'Or.
