Asamoah Gyan says Ghana was "tactically perfect" in its 2-2 draw with Germany and believes the Black Stars should "go all out" when they meet Portugal in their final World Cup group game.
The west Africans came from behind to go 2-1 up through Andre Ayew and Gyan but a Miroslav Klose goal rescued a point for the Germans in a thrilling encounter.
And Gyan praised and congratulated his team for the performance against Joachim Low's side.
"It was a great game," he told BBC after the game. "I’d like to congratulate the team, we believed in ourselves. Against a top team like Germany, we had to fight to the end and it was a fair game today.
"I think it was great work, tactically we were perfect today. They are good in possession. What we planned today worked really well for us."
Gyan's goal was his fifth in a World Cup finals, making him the joint-highest scoring African in the competition with Roger Milla, and he admitted he was low in confidence after missing the a lot of chances in the 2-1 defeat to USA in their first game.
"I was just waiting for my chance to happen, I had a couple in the first game so I was a bit nervous."
In order to progress into the second round, Ghana needs Portugal to beat the USA on Saturday night and then must beat Paulo Bento's side itself, and Gyan says his side must attack in its last game.
"I think we should go all out because a draw isn’t enough. We must focus and after what happened today, we should be positive."
