Pato welcomes new AC Milan teammates Ibrahimovic, Robinho
The Rossoneri have always looked to Brazilians and added to the list with the deadline day transfer from Manchester City.
"I am very happy that Robinho is joining us, even if we haven't yet talked about Milan," said Pato on international duty.
"Competition is not a problem, as we must all give our absolute best this season," continued Pato.
"We are a great squad and will try to go all the way both in Serie A and the Champions League."
