The 32-year-old striker has scored twice in three matches for Corinthians following his return last week from a knee injury which kept him on the sidelines for a year.

Ronaldo was not included in Brazil's squad for the upcoming World Cup qualifiers against Ecuador and Peru, which was named today.

And Dunga admits the former FIFA World Player of the Year will need more matches under his belt before he can be considered for the Selecao.

When asked whether he is ready to pick Ronaldo, Dunga said: "Not yet. I will deal with that calmly when I have to.

"But like all Brazilians I'm supporting Ronaldo. I'm happy he is back and scoring. He is doing what he does best."

Dunga does, however, understand why there have been calls to bring Ronaldo back into the Brazil squad and has left the door open for the striker.

"They are not doing that (calling for his return) because of the two goals he has scored, but because of his career," the coach continued. "Football is emotion, it's passion.

"As soon as we believe he is playing well, and his fitness is good, then we'll name him. Ronaldo hasn't got anything to prove to anyone."
