Analysis Germany last won the World Cup in 1990, coincidentally beating Argentina in the final (four years earlier it was the reverse outcome between the same opponents).
Since then they have completely changed their philosophy as a nation, and at academy and senior levels in terms of domestic development. They are now reaping the benefits and while Spain have been the role model for the last decade, this is Germany's time.
Their strengths include positional discipline, an understanding of how to press as a team, and the mobility and versatility to rotate in midfield.
In Miroslav Klose, they also have the man who has scored the most World Cup goals. The Germans will keep the same formation for the final, with Thomas Mueller on the right running in behind Klose.
Analysis 28 years ago Diego Maradona single-handedly won the World Cup for Argentina now it is Lionel Messi's chance to create a legacy. Pundits have been talking about Messi and the way he has carried Argentina but there should also be praise for Javier Mascherano.
He has been excellent in this tournament, even after being knocked unconscious against the Netherlands.
I think Germany will almost certainly control possession, so it will be important for Argentina to be aggressive and play with a high line. They will look to start possession from as deep as possible, with Mascherano splitting the centre-backs with the aim of playing a penetrating pass into midfield or a killer pass behind the full-backs.
I believe Alejandro Sabella should start Sergio Aguero and allow him to play as a No.10, letting Messi run in behind or go one-on-one, but he is more likely to select Gonzalo Higuain.
