Were Europe's top stars too tired to shine?

Thanks to Bastian Schweinsteiger and the rest of DIE NATIONALMANNSCHAFT, ARGENTINA never looked likely to defeat DEUTSCHLAND today, let alone score.
As I watched today's WORLD CUP QUARTERFINAL (on UNIVISION, so I could enjoy the commentators shouting ¡GOOOOOOOOOOL!) all I could think about was the utter flop of some of the biggest stars in European football.
What happened to Kaka, Wayne Rooney, Didier Drogba and Lionel Messi -- among others -- in this tournament?
Why didn't the stars of the domestic scene shine on this bigger stage?
Messi looked sadly, pitifully out of his depth against Germany today.
Were Europe's stars too tired to compete?
Germany's strength up front comes from players such as Lukas Podolski and Miroslav Klose -- players who didn't exactly steal the spotlight during the Bundesliga season.
It hasn't really been a tournament for Europe's stars. Are their domestic duties to blame?
