The Reds have seen their finals hopes take a dive after shooting themselves in the foot on more than one occasion this season.

But the United coach hasn’t given up on a favourable result in Gosford when Newcastle tackle Central Coast and feels his side can get the job done in Perth.

“Although the equation is quite difficult we still want to go out on a positive note and first thing’s first, we’ll worry about Perth this week,” said Vidmar.

“They’re a good side, very fast in the midfield and obviously with Lazaridis he’s a real danger and Harnwell is going to be a threat up front. We just need to match their intensity.”

“They (the players) were quite dejected after the game (at Newcastle) in the changeroom. It’s never nice but it’s happened, we just need to focus and there still a lot of pride to show and we really want to finish off the last two weeks on a positive note.”

Nathan Burns, Robert Corntwhaite, Jonas Salley and Cassio all return to the line up while Bobby Petta and Diego are sidelined with niggling injuries.

Injuries have been the story of the season for the Reds with a number of soft tissue injuries robbing Vidmar of his most influential players.

However the club plan to have an inquiry into the reasons behind the crippling trend and will look to rectify the situation for the ACL and A-League version four.

“We’re having a big look into where we’ve gone wrong,” said Vidmar. “We’ve identified quite a few areas where we need to improve, so that’s already started and we’ll make sure we get that right for next year.”
