"I am happy," Ronaldinho admitted afterward in an interview with Sky Italia. "Milan put me in a condition to work well, so I arrive with the confidence and enthusiasm to do what I want."
He admitted everything is going well with first-year coach Leonardo, in contrast to the troubles he had last season with Carlo Ancelotti.
"It's normal that when I don't play, I'm not happy," he said. "I play regularly with Leo and am in good shape, so it's going well."
Ronaldinho, who says he just wants to win something for Milan, started for Brazil on its 2002 World Cup championship team and on its team that fell to Brazil in the quarterfinals at the 2006 World Cup, but his poor form in recent years cost him a spot on Dunga's Brazil team that won the 2009 Confederations Cup and qualified for the 2010 World Cup as the South American champion.
Dunga recently said he was pleased to see that Ronaldinho is enjoying himself again and did not rule out his return to the national team.
"I have seen Ronaldinho smile on TV," said Dunga. "It seems like a detail. Instead it's an important 'report.' Dinho makes the difference when he is happy."
Dunga also liked that Ronaldinho was working hard.
"The doors to the Brazil side are not closed," he said. "I still have six months to choose the players. Ronaldinho needs to continue like this, remembering that in soccer the past doesn't count. All that counts is the present."
For Ronaldinho, a recall for South Africa 2010 would be a dream come true.
"My wish it to go there and bring another trophy to the Brazilian people," he said recently.
