mistake in Belgrade, yes : not letting Simon play the final match ... one can say it's a big one, but well
If France can take benefit of Argentina being out (they would have to play in Argentina, Del Po's decision may have an unbelievable impact this year, it was a great chance for Argentina even more than for Switzerland), they would receive Germany, Czech Republic, and Serbia or Spain.
At home, they would surely have a big chance to defeat those teams.
