SAO PAULO, Brazil (AP) -- Despite talking to Manchester City and Paris Saint-Germain, Ronaldo says he wants to play for Brazil's Flamengo next year -- but may retire if he fails to get back to his best.

"If in January I feel that something is missing, if I realize that I won't be able to play as well as before, I will retire," Ronaldo said.

The three-time FIFA Player of the Year, now almost fully recovered from his latest serious knee surgery, told Brazil's Globo TV late Monday that his playing time in Europe may be over even though some top clubs have shown an interest in him.

Ronaldo said he had "very interesting talks with Manchester City," and that Paris Saint-Germain "has been showing a lot of interest," but his first choice will be Flamengo, Brazil's most popular club.
