Rio de Janeiro, June 5 (IANS) Ronaldinho has signed up with Atletico Mineiro four days after quitting rival Brazilian football club Flamengo.

Athletico Mineiro confirmed Monday they had signed on the 32-year-old on a one-season contract for an undisclosed fee.

He trained with the team Monday afternoon and is expected to make his first appearance for the club in Wednesday's Brazilian Serie A championship match against Bahia.

I returned to Brazil to win titles and now I have a new opportunity, Ronaldinho said at a press conference in the city of Belo Horizonte.

I am motivated and focused on doing my best. I feel like I still have many good years left in my career, he said.

The two-time FIFA world player of the year sought a court injunction in Rio last Thursday to end his contract with Flamengo.

He also revealed plans to sue the club for reportedly $20 million in unpaid wages and bonuses, Xinhua reported.

What happened with Flamengo is in the past. Now it is a new phase in my career and my future is with Atletico, the former Barcelona and AC Milan star added.

Atletico Mineiro have not won a major trophy since 1997 and have just one top-flight league title to their name in 1971.

The club's president Alexandre Kalil refused to disclose Ronaldinho's salary.

I can't talk about his salary, Kalil said. But Atletico will be able to pay for it by themselves. We won't need the help of a partner. He is not just any player, he is Ronaldinho. I have a reputation as a madman but I am not mad enough to turn down the chance to sign Ronaldinho, he said.
