Inter Milan and Portuguese legend Luis Figo says the talent of Manchester United star Cristiano Ronaldo has no limits.

"He has enough quality to do whatever he wants in the game," gushed Figo. "I think if I had his quality, I wouldn't have had to work so hard in my career!

"He's fast, good in the air, strong, technically perfect ... he is very complete."

Asked if he believed former club Real Madrid could land Ronaldo, Figo declared: "I see that as difficult because he plays for a big club and is happy there. But you never know.

"You never close doors, because everyone wants to always improve."
