Brazil great Ronaldo has yet to make a decision about his playing future after undergoing knee surgery.
''I really, really want to play again. My heart says yes but I'll have to see what my body says,'' the AC Milan striker told a news conference before leaving the La Pitie-Salpetriere hospital in Paris.
The three-time World Player of the Year, 31, ruptured a knee ligament ten days ago and is out for at least the rest of the season.
He said the injury was ''tough blow physically and an extremely tough one mentally''.
''Right now all I'm thinking about is getting better,'' said Ronaldo, who will stay in Paris for ten days before having his stitches out and returning to Milan to start a nine-month rehabilitation. Milan Vice President Adriano Galliani on Friday's cited Lyon's Karim Benzema, Arsenal's Emmanuel Adeyabor and the Chelsea pair Didier Drogba and Andriy Shevchenko as possible replacements for Ronaldo.
Milan need a fourth striker, and all of the above 'would do fine,'' he said.
But he added: ''I'm not going to talk about the transfer market until May''.
For the moment, he said, Milan was ''OK' with Alberto Gilardino, Filippo Inzaghi and its new Brazilian striker Alexandre Pato.
He did not discuss the possibility of Milan not offering Ronaldo a new contract when his present one runs out in June.
Ronaldo ruptured the main tendon in his left knee against Livorno on February 13 - a very serious injury that often spells the end of players' careers.
The record scorer in World Cup history suffered a similar injury to his other knee in November 1999, while playing for Milan's cross-city rival Inter.
Top Paris surgeon Gerard Saillant repaired the break and he supervised the latest surgery.
On his first comeback in April 2000, Ronaldo only lasted seven minutes before the tendon snapped again.
After more thorough reconstructive surgery in Paris, he was out for another 20 months.
This season, since joining Milan from Real Madrid, a new slim-line Ronaldo has scored nine goals in 16 matches despite nagging injuries.
When Ronaldo returned for Inter late in the 2001-2002 season he was soon his old self again and scored twice against Germany in the 2002 World Cup Final as Brazil became world champions for a record fifth time.
At the next World Cup in 2006, he scored against Ghana to bring his World Cup tally to 15, one more than German great Gerd Mueller.
