Brazil coach Dunga is surprised that Adriano has gone AWOL from Inter Milan.

The Inter striker was not on the flight back to Milan and is not answering calls from his mother or his agent.

"I didn't see him sad or depressed," explained Dunga to Telelombardia television.

"He was happy, singing and dancing like he always does when he's on international duty with Brazil.

"We booked the flight for his return, as we do with every player, but since then I haven't heard anything. Nobody has spoken to him or knows where he is.

"I must admit, now I'm very worried about this too."
