Vidosic and Van Dijk fit for Adelaide

Hamstring injuries forced both out a fortnight ago, but midfielder Zenon Caravella said both were pressing for selection for a match that could send Adelaide through the group stage.

"They have been training well and look fit and sharp," Caravella said on Monday.

"I'm sure they're up for selection, it's just a matter of what Kossie (coach John Kosmina) decides to do and what formation."

United enters the Hindmarsh Stadium fixture top of the group, three points clear of Bunyodkor and Korea's Pohang Steelers.

Adelaide downed the Uzbek side 2-1 in Tashkent but Caravella noted that was six weeks ago, when Bunyodkor had just started its domestic season.

"They were a good side over there when we played them and we're expecting them to be a tough side," Caravella said.

"They're a good footballing team, they pass it around quite well and have got some fast players on the wings."

But Caravella hoped Bunyodkor's need for a win with just two group games remaining could play into Adelaide's hands.

"They have got to win," he said.

"I'm expecting an open game, I'm expecting them to attack us - which will suit us."

Adelaide is best placed of the Australian teams to advance in the Asian competition.

"It would be massive," said Caravella of the Reds, who finished second bottom in the A-League.

"We're in a good position at the moment but nothing is set in concrete obviously.

"But to finish the A-League season they way we did - to do well in this competition now would be huge for us."
