Ghana manager Millovan Rajevac is remaining cautious of a wounded Australia ahead of the World Cup clash between the two nations on Saturday.
Australia were disposed 4-0 by Germany in their Group D opener whilst Ghana managed a hard fought 1-0 win over Serbia but Rajevac knows the Socceroos will be determined to bounce back in a positive fashion and is erring on the side of caution.
"It's going to be a very difficult match," Rajevac said. "This is the match of the season for us.
"We have to prepare well and concentrate because nothing is over before the final whistle. We need to be very focused and be at our best if we want to get a victory.
"For Australia this is their last chance and they will give their best. We all know how competitive Australia is as a nation, they will do everything they can to get a win.
"They are a very strong team. The performance against Germany was not a true reflection of their ability.
"Germany scored their goals at good times and afterwards Australia had a red card, so it was easy for them to finish the match and score more goals.
"They can do much better, they can run much better and that is what we have to be ready for. We have to respect them."
