Ghana striker Asamoah Gyan says he is unsurprised to be a star at the World Cup as he went into the tournament fully fit.
The striker has netted three goals to help the Black Stars into the quarter-finals for the first time, including the extra-time winner against Group C winners USA in the last 16.
It is a welcome change of fortune for the striker after he was close to quitting the African Cup of Nations two years ago following criticism from Ghana supporters.
The Rennes striker is now looking forward to adding to his goal tally in Friday's quarter-final clash with Uruguay in Johannesburg.
And the 24-year-old, who has recovered from an ankle knock ahead of the game, has also set his sights set on playing in the English Premier League following the tournament.
Gyan said: "I did expect to score goals here because I did so well for my club and the confidence is there.
"I've scored many goals for my club. I am not surprised. When I am 100% fit, I know what I can do on the field.
"I am not surprised to be a star here. I know what I am worth when I am 100% fit. I thank God for that.
"People compare me with big names like Lionel Messi and I'm very happy to hear that. They are the best strikers in the world.
"You also have to remember that two years ago I was criticised by my compatriots.
"It hurt. But I never lost trust in myself. I knew that when 100% fit I would perform and that is what has happened."
Gyan admits a laid-back approach - including singing - has helped Ghana become only the third African nation after Cameroon and Senegal to reach the last eight of the World Cup.
He added: "Uruguay are a difficult side but we don't care who we are going to play against. We are ready to play anyone.
"I don't think that is a problem. We shall go there and play our hearts out and we will come out victorious.
"We know all of Africa is supporting us. We are the only African team left and we want to make everyone happy.
"We know how to psych ourselves up before the game. That is the key to our success.
"Sometimes we sing all the time, we just forget about the game, and make sure we consider it on our terms because we know what we can do on the field."
