Brazil coach Dunga had no qualms including Manchester City star Robinho in his squad for their friendly against Italy.
The British record signing was questioned by police on Tuesday and issued a statement on his website denying any "wrongdoing or criminality".
And, ahead of Brazil's friendly with Italy at Emirates Stadium on 10th February, Dunga has backed the former Real Madrid player.
"I have no reason to doubt the word of Robinho," said Dunga.
"He is a player on whom I have been able to count every time I have needed him and who has shown exemplary professional behaviour when he has been in the national squad."
