#4 France can dominate the midfield
If we look at the midfield of the past two teams that have won the World Cup in 2010 and 2014 we can conclude that not only a good defense but both Spain and Germany had a midfield as well.
This helped them dominate the game for them and provided them with an extra man both in attack as well as defense.
The French midfield right now looks very solid with Kante, Pogba, Matuidi and Tolisso. While for Argentina only Banega has turned up in the midfield and based on current form and individual ability it looks like France have an upper hand.
Their domination in the midfield would definitely give them an advantage in the game and it would help them open up Argentina's defense and at the same time frustrate them when they are attacking.
