Adelaide duo out of opener

Brazilian duo Cassio and Diego will miss Adelaide United's FIFA Club World Cup opener against New Zealand's Waitakere United on Thursday for a spot in the quarter-finals.

"Definitely they are out," Adelaide coach Aurelio Vidmar said Wednesday.

He said Cassio has had a "high fever" since Friday and struggled during practice this week. "He wasn't looking good, so we don't take any risk," said Vidmar.

For sure, it's probably not our strongest line up, but we've got confidence.

Diego was out due to a tight groin, he said. "We thought he would be all right for tomorrow night. But it's still a little bit sore. We really don't want to take a risk," said Vidmar, adding that Diego would hopefully recover in time for the next game.

Vidmar appeared confident without the Brazilian duo, saying: "Strong players will come into the squad. We expect them to do their job. For sure, it's probably not our strongest line up, but we've got confidence."

A 6-1 win over the Wellington Phoenix on Friday lifted the Reds to the top of the A-League.

A win over Waitakere would give the Australian club a chance to avenge Gamba Osaka of Japan for their defeat in the AFC Champions League final, with giants Manchester United awaiting the winners of that showdown in the semi-finals.
