Former Brazil star Ronaldo hopes to come out of retirement and play for American second division side Fort Lauderdale Strikers, although he concedes it will be hard to regain match fitness.

The 38-year-old took part-ownership in the North American Soccer League side last month and he was presented to the media on Thursday.

The first question put to the World-Cup winner was, unsurprisingly, whether he might play any games for the club, and Ronaldo confirmed he would like to be involved if he can.

The ex-striker, who hung up his boots four years ago, said in English: "That is not easy because I love to play, I love soccer, that is what's been all my life. My big love is soccer and when I retired, stopped playing, it was because of my body. I had so much pain, so many injuries, that's why I stopped.

"It's easy to get into shape, you have to train - just that, but to play a soccer game you have to be in very good shape.

"I will try. For myself, it's another challenge, I'm sure it will help the league, it will help the team and you have the soccer in I will try, I will train a lot. And if the trainer (manager) needs me I will be (there) . Maybe. I will train to play some matches, especially if we will get into the final again."

He reiterated: "So I hope so. I will train a lot, but our goal is to make the sure the Strikers is going to be bigger."

The former Real Madrid, Barcelona and Inter Milan forward won two World Cups in 1994 and 2002, scoring eight times in the latter to claim the Golden Boot Award.

He was also named FIFA World Player of the Year three times, won the Ballon d'Or twice and is second only to Pele in Brazil's scoring charts having netted 62 times in 98 appearances.

Ronaldo called time on his career in 2011 after two years at Brazilian club Corinthians, and since then he has been a partial owner of 9ine Sports and Entertainment agency, whose clients include Barcelona striker Neymar and mixed martial arts fighter Anderson Silva.

Fort Lauderdale were taken over by three Brazilians last September and it was announced in December that Ronaldo would be joining the ownership group.

Ronaldo is not the first high-profile player to join the Strikers, with Gordon Banks, Gerd Muller and George Best also taking roles with the club in the past.

At Thursday's press conference Ronaldo said: "It's a pleasure to be here, it's an honour to be part of this team.

"I thank my partners for trusting in me. I'm sure we will continue the history of Fort Lauderdale Strikers and for sure we will make this team a big team. We will work hard on this.

"I wish good luck to us, and let's work!"

The Strikers, who were beaten by the San Antonio Scorpions in The Championship Final last November, open the 2015 NASL Spring Season at home to New York Cosmos on Saturday, April 4. Cosmos have signed Ronaldo's former Real Madrid strike partner Raul.
