Lessons learned at the last World Cup have Ghana poised to sweep aside Australia and qualify for the second stage of this year's tournament.
That's the view of striker Asamoah Gyan, who's goal against Serbia in Ghana's Group D opener left his side on the brink of qualification for the second round.
"We learned a lot of things against Brazil," said Gyan, who believes the 3-0 second stage loss to Brazil in 2006 proved a good lesson for the his side.
"I think there is a big difference in that we've gained a bit of experience in the World Cup.
"In 2006 we did quite well, we went to the next stage, but this time Ghanaians are expecting more from us.
"That is why we are also going like wounded lions."
Gyan is proving himself a big tournament specialist, scoring Ghana's first goal in a World Cup finals in 2006, its opener in 2010 and starring at the African Cup of Nations earlier this year.
The 24-year-old striker's eyes must have lit up when he saw the holes punched in Australia's defence by Germany's clever play in the attacking third.
â€This World Cup I was going there to just make sure I keep doing what I have been doing," he said.
"I was saying to myself, 'if you score once again you can be the happiest man'.
"So when I was playing I was just concentrating, and I knew, I would score. I knew I would score, definitely."
Ghana dominated the midfield against Serbia - an area Germany bossed against Australia.
Even without injured skipper Michael Essien, Inter Milan star Sulley Muntari, who sat on the bench, and skipper Stephen Appiah who was a second half substitute, Ghana had a clear advantage.
Muntari looks certain to return to the starting side against Australia.
