There will be many terrific match-ups of course, which brings us to Lionel Messi. I don't think he will be man marked as it is impossible to contain the little master for an entire game. The Germans will instead aim to close down the service he receives.
Another key factor for the Argentinians will be the fitness of Sergio Aguero. If the marksman has survived his cameo against the Netherlands, he will pose a big threat.
The Argentina set up will not allow Germany to leap from defence to attack as they did against Brazil. While the Germans will endeavour to move the ball quickly to get Thomas Muller and Mesut Ozil in one-on-one situations with defenders, the Argentine wing backs Pablo Zabaleta and Marcos Rojo will cause the German defence greater problems. And if Angel di Maria has recovered from injury he will be another thorn in the side.
It is fascinating to contemplate how the tactical battle might play out, but little things such as lack of concentration at a set piece, not picking up an opponent tight enough, even a slip or misdirected pass often turn out to be the difference between ecstasy and agony.
Argentina have been my pick from day one. If they do win, it would provide fitting glory for the world's best player, Messi.
