"It is true that Flamengo are interested in me, but I have never said or written anything about this matter," Ronaldo told Milan Channel.
"My desire is to earn my place at Milan because this is the team where I want to play, the club that always put faith in me. What counts now is that I feel good and want to return to playing football."
He played 45 minutes in today's 2-0 friendly win over the United Arab Emirates in Dubai and hopes to make his Serie A comeback at the weekend.
"After this friendly I can say I am in good shape and at the Coach's disposal for the Serie A game against Napoli."
