#3 A defensive reboot
One of the important reasons Argentina reached the finals of the Copa Americas and the FIFA world cup in recent years, is the solidity of Argentina’s defence.
However, Argentina’s defence has been an important reason for Argentina’s failure in the last couple of years. This was widely exposed against France when the defence simply couldn’t contain the French attack and could've easily let in more than 4 goals. The current defence has become slow.
It’s time for a reboot, and that's precisely what Argentina should be doing- Build a young defence, as they’ll have gained enough experience for the FIFA World Cup in Qatar, by playing in the next 2 Copa Americas.
Besides, if Simeone comes in and prepares to set up a defensive gameplan, the pace would really help add to the the physical supremacy of his teams at the back. A defence which is pacy and strong would work very well for Argentina.
