Brazil coach Luiz Felipe Scolari was at the Milan derby last night.
Scolari has been linked with a European return in recent days.
"I am here to watch the game and the Brazilians who are on the field," said Felipao.
"Is Kaka among them? He has to take part in the games and be useful to the team. We'll see... Everyone has the possibility of being called up."
