Brazil coach Dunga is delighted to see Ronaldinho starring for AC Milan this season. However, Dunga says a return to his squad in time for the World Cup is no guarantee.

He said: "I have seen Ronaldinho smile on TV. It seems like a detail. Instead it's an important 'report'. Dinho makes the difference when he is happy.

"For him the ball is his happiness, not his job. I have also seen him fight, run and suffer behind an opponent. Other positive signals.

"I follow him. I await him. The doors to the Brazil side are not closed. I still have six months to choose the players. Ronaldinho needs to continue like this, remembering that in football the past doesn't count. All that counts is the present.

"Public opinion would like Dinho in South Africa. But this is normal. The people support those who are out of the squad. It also happens in Italy, right? I read that the fans would like to see Cassano or Totti."
