Ronaldo has claimed Manchester City are one of two options he is considering as he looks to find a new club.
The former World Player of the Year is in South America working on his fitness after a serious knee injury curtailed his time at Milan.
“Flamengo and Manchester City are two options,” Ronaldo told Brazilian website Terra. “But nothing more than that.
“There is nothing concrete.
“The most important thing is that there is interest from big teams.”
Ronaldo also revealed that he hopes to regain his place in the Brazil squad once he returns to full fitness.
“It’s clear that I have nostalgia for the national team but I am continuing with the utmost calm,” added Ronaldo.
“I want to first return to the right spot physically and then come back to play and then think about Brazil.”
