Ronaldo has no plans for retirement as he chases a contract at Manchester City.

Ronaldo, who has been training with Flamengo, cannot wait to get back on the pitch and prove his doubters wrong.

"I want to stop playing when I decide, not because I have been forced to by an injury," he told Brazilian magazine Trip. "In the book of my career there are still a lot of blank pages to write upon, and I want to finish while scoring goals."
