Miroslav Klose has revealed he wants to stake his claim for a place in the Germany squad at the World Cup in 2014, but only if his fitness permits him.The 33-year-old striker has been on the international scene since 2001, scoring 63 goals in 114 caps for die Mannschaft, and he now wants to extend his career further by representing his country in Brazil."If I feel physically fit, the 2014 World Cup in Brazil is an achievable goal,” Klose told 11Freunde.The Biancocelesti hitman was then quizzed on what has been the determining factor behind Germany’s return to the upper echelons of international football, and he put their renaissance down to the development of more versatile footballers."The team has become much more flexible, we can play different systems,” he stated. "Toni Kroos, Bastian Schweinsteiger, Mesut Ozil are all incredibly versatile.”As well as experiencing renewed success with Germany, Klose has also rediscovered his joy at club level after a fine debut season with Lazio. When asked about his training habits in Italy, he touched on the absence of an audience at sessions."As a player, you can concentrate more on training. The sessions take place without an audience, which was different in the Bundesliga.”And despite the lure of Roman night life, Klose admits he was never one for partying: "I was never a guy for long evenings and discos. I’ve always been completely focused on football.”
