World Cup winner Ronaldo is delighted with his continuing recovery from a serious knee injury and hopes to make his Corinthians debut next month.
The former Real Madrid and Barcelona striker damaged cruciate knee ligaments in April last year playing for AC Milan and has since signed a contract with the Sao Paulo club in his native Brazil.
"My progress is marvellous," said Ronaldo. "I am losing a lot of weight and gaining strength, but I don't know yet when I will play.
"I will not rush my debut. I will be available when I'm 100%, not sooner. I will not be ready on the 17th (for a friendly against Argentinian side Estudiantes) or even this month. Maybe in February."
Although the injury was initially considered career-threatening, the 32-year-old maintains his desire to play professionally is as strong as ever.
"My motivation is to play football," he said. "My love for this sport is huge. When I am on the field I am the happiest man in the world.
"The demands of training are hard and in the games it'll be 10 times more so."
