Adriano is unsettled at Roma and appears to be contemplating a move back to Brazil just a couple of months after his return to Italy.
The 28-year-old has played just 65 minutes this season and is behind Mirko Vucinic and Marco Borriello in the pecking order up front.
"I don't want to leave Roma just like I didn't when I left Inter," Adriano told Brazilian paper Extra.
"If it were down to me I would be open to going back to Brazil. But you'd need an agreement between the clubs otherwise I am staying here until 2013."
Asked if Ronaldo had been in touch about joining Corinthians, Adriano said: "He called me. But I told him that I have a contract until 2013.
"I want to get back to playing. I am physically healthy, but I don't know if I figure in the Coach's plans.
"I need to play. I am no longer a little kid and I can't waste time because the years are passing," he concluded.
