Reports he will go to the World Cup over Martial and Fekir despite barely playing in comparison to them this season.
Even Deschamps knows that even if the other two possibly deserve it on merit(At least Fekir), he just cannot leave this guy out as his potential level of impact is just enormous compared to the two.
It's similar to how Joachim Low and Andreas Köpke kept MAtS in the Germany team when he wasn't playing regularly or struggling despite calls for Timo Horn, Bernd Leno, Fahrmann and others to be selected over him. They knew he was going to succeed Neuer and become a World Class GK.
