Ghana coach Milovan Rajevac has warned his side to be mindful of complacency when they play Australia in their second World Cup game, despite the Socceroos' 4-0 thumping at the hands of Germany.
"The Australian team is a very strong team," Rajevac told ghanafa.org.
"Their performance against Germany did not show the real picture. They can do much better, can run better, so I expect them to be much better than the performance against Germany."
The 55-year-old Serbian led his side to defeat his home country last Sunday, making them the first African team to secure three points. He says the Black Stars are now ready for the Socceroos.
He added: "For Australia, this is the last chance. So they will give their best. They are a very competitive nation and I am sure they will give off their best in the next match so we are ready for that.
"For us this win is very important... we need to prepare well and concentrate well."
