The Argentina goalkeeper Sergio Romero says his team are studying Germany's penalty techniques ahead of their World Cup quarter-final in Cape Town on Saturday.

Diego Maradona's side are hoping to avoid a repeat of the 2006 quarter-finals, when Germany beat Argentina 4-2 in a shoot-out.

Romero said it was a "smart move" by the Germans, adding that Argentina were copying the tactic by studying videos of how their opponents take penalties.

The Argentina forward Carlos Tevez admits he cannot bear to think of losing Saturday's quarter-final. The 26-year-old Manchester City player said: "Why not think I can be a champion? Every night, I do.

"I have a hunger for glory so great that I cannot imagine the great sadness there would be without the cup. I could not bear to lose on Saturday."

Tevez's all-action approach and skill have made him a crowd favourite, and he is desperate to deliver the biggest prize of all for the fans. He said: "It makes me really happy. It must be my way of playing. I give everything for every ball, and people identify with that.

"Hopefully, with all the boys, we can give them the joy we all hope for."
