Manchester City manager Mark Hughes has played down reports that Robinho returned home because of his club's failed bid to sign fellow Brazilian Kaka.
There was speculation that Robinho made a sudden exit because he was distraught that Kaka would not be joining him at Eastlands.
But Hughes said: "Robbie was already on a plane to Brazil before the Kaka deal was dead and buried. People linking the two are trying to cause a little bit of mischief."
Robinho phoned Hughes to give his reasons after publicly stating he needed to address a family matter. He claims he will be ready to face Newcastle on Wednesday.
He will still be in hot water, however, and seems certain to face disciplinary action for his behaviour.
"Robbie rang me, and we had a brief chat - given the language constraints " Hughes told Manchester radio station Key 103.
"He understands we need to address this situation - and we will.
"Once he is back we will sit down. We will make sure everyone is clear (about the situation), and I will make my feelings known.
"I will be looking for a more detailed explanation from Robbie why he felt the need to go back - and then decisions will be made.
"He left the training camp without permission. He said he had personal things he needed to address and made the decision to go back to Brazil. That was wrong."
