They were just a few words, but they were powerful ones: "Show to the world that you're better than [Lionel] Messi, show that you can decide the World Cup."And with those words of inspiration, Germany coach Joachim Loew ushered Mario Goetze onto the field late in Sunday afternoon's final, a 22-year-old sub for veteran Miroslav Klose, the World Cup's all-time scoring leader. Some substitute players would have laughed at the idea their coach was saying they were better than a revered player who's been named the world player of the year four times. But Goetze took it seriously, and he went on to score the only goal of the match in the 113th minute, leading his team to its fourth World Cup title.
