Reds aiming for three points

Adelaide United will be without classy midfielder Diego for its Hyundai A-League clash against Queensland Roar at Suncorp Stadium on Friday.

Adelaide United will be without classy midfielder Diego for its Hyundai A-League clash against Queensland Roar at Suncorp Stadium on Friday.

But the Reds won't be tempting fate by rotating too many other players for the clash with coach Aurelio Vidmar keen to keep his squad motoring ahead of their ACL semi-final clash in Uzbekistan next Wednesday.

Diego, who was a goal scorer in United's ACL win over Bunyodkor on October 8, was struck down by a virus earlier this week.

The Brazilian took to the training track on Thursday but coach Aurelio Vidmar said the club wouldn't push him as his health improves.

"He won't be playing tomorrow night. He was probably crook for three days so it's best he rests. He did a little bit of work today and he'll do a little bit of work tomorrow and get him right for next week," Vidmar said.

United made wholesale changes to its starting line-up when it tackled Sydney FC back on September 20 and paid the price losing 3-0.

Keen to keep a firm footing in the top four and some winning momentum, Vidmar said in some ways it was a positive that Socceroos Robbie Cornthwaite, Paul Reid, Eugene Galekovic and Scott Jamieson weren't used against Qatar.

"All those boys with the national team will come straight into the team and Jonas (Salley) comes in," he said.

"We are trying to play the strongest possible side tomorrow night and trying to get the three points because it's still extremely important what we are doing in the A-League."

"Whatever happens after Friday night's game we'll assess on Saturday morning."

Vidmar said it had been a challenge preparing for the Roar game with four of his key players away training with the Socceroos.

But he thought the quartet should return to his line-up full of purpose.

"They'll certainly get a massive lift in terms of motivation. I spoke to Pim and he said he was very happy with the work they did during the week so that's obviously going to lift their confidence," he said.

"It's been quite intense so they assure me they are all fit and healthy …so everyone should be fine."

Meanwhile Vidmar is wary of the Roar who've beaten top side Melbourne Victory and drawn with Sydney FC in the last two rounds.

They also proved one of the Reds' toughest opponents - the South Australians holding on for 1-1 draw the last time the two teams clashed.

"We gave them a little too much room, they've got a great midfield with (Massimo) Murdocca, (Matt) McKay, Charlie Miller has been in very good form and good goal scoring form," he said.

"They are a midfield that are extremely mobile and a lot of times we struggle that sort of midfield. If we keep everything tight so we shouldn't have too many problems."
