Real Madrid hero Ronaldo can see AC Milan goalkeeper Gigio Donnarumma moving to the European champs.
Donnarumma's future is now set to be settled with Italy's U21 Euros campaign now over.
Ronaldo told Gazzetta dello Sport: "I'm not close to Donnarumma, but I say that we have to be careful to judge: he has a clear right of choice, or must be able to choose where he feels more valued and motivated, which can also mean in Milan, of course.
"Everyone has his own challenges, this must be accepted. I have changed so many teams, this is true: they have often been hard choices but I have always been close to Real Madrid.
"The market is not my skill, I read that Donnarumma is liked, but it is normal: in Real the great players are always welcome, there is almost a duty to monitor them."
