Germany's wonder boy Mario Goetze

German coach Joachim Loew revealed he told Mario Goetze to prove he's better than Lionel Messi before Germany's miracle boy hit the extra-time goal to win the World Cup final. Goetze came off the substitutes bench to score a stunning 113th-minute goal as Germany beat Argentina 1-0 at Rio de Janeiro's Maracana Stadium. "I told Mario Goetze, 'go out and show the world you are better than Messi'," said Loew. "Goetze is the miracle boy, he is the wonder who can play in numerous positions, he is the decider who can come on and make a difference and that is what he did ."
