Germany's game looked pale right from their first encounter with Mexico. They were very less on energy, no enthusiasm, no lust for title, henceforth they demolished.
That's true but most people thought that they will qualify at least at the second position. For me, Germany had to be disqualified earlier if the referee counted Sweden's penalty kick. but teams like Belgium and England have shown their capabilities.
And i think tomorrow we should see the best game in this world cup 
About title claimer, my bid is still with Argentina.
It will be a surprise from a team that barely qualified to the world cup then to the round of 16. Argentina is far from its real performance and wouldn't have a big chance against France. Löw should go, but he'll probably just leave and won't be fired. There is no one who could raise his voice against him. This circle around Löw/Bierhoff is almost untouchable.
It´s his decision if he wants to continue or not. Wouldn't surprise me to see some players announcing they won't play for the NT anymore.
As for Argentina and France their can be a lot of surprises yet France is still not that convincing and Argentina could wake up after all what happened so it will be difficult to see the outcome of the match
