Pato, 17, was signed from Internacional last week but will not be eligible for the Milan first team until after Christmas.

Ronaldo, 30, believes that when he is eligible Pato should immediately be blooded by the Rossoneri.

Ronaldo told www.gazzetta.it: "I think he (Pato) is ready for our championship.

"There are no norms that say if you do not weight enough or are not old enough - it depends what you can do with the ball."
