The former Inter star ruptured tendons in his left knee during Wednesday´s 1-1 draw against Livorno and underwent surgery in Paris 24 hours later.
While at Inter eight years ago Ronaldo beat the same problem and Moretti is confident he can do it again saying: "I hope Ronaldo returns to play as soon as possible, although at this time you can consider the injury as career-threatening, just as it was in 2000. But in him there´s a significant mental strength and a strong physique."
