It all went perfect for the Qataris. Best World Cup Final ever, with the 2 mega-stars belonging to the same, Qatari-owned team, and both delivered a great deal of football in the tournament and during the game.
Scaloni did a genius tactical move to start with Di Maria on the left side and exploit the weakest of 2 French sides. Deschamps risked by having both Giroud & Dembele in the starting squad. The fact that he subbed them before the half break shows, in my opinion that he was considering this move right from the start.
From then on, Deschamps threw inside everything he had, even going as far as to sub Griezmann and Hernandez and left France spineless at 4-2-4 and without experienced players in the shoutout.
On the other hand Scaloni did the mega mistake to sub Di Maria something that immediately weaken the Argentine agility and penetration. A terrible decision that he almost payed with a loss.
Thankfully for the Argentines they had Emile Martinez a penalty magician, who realised that no.2 & 3 takers were young and unexperienced and he physiologically bullied them; Note how he was standing in front of Coman (taker No.2) and how he threw the ball so Tchouameni (taker No.3) to go and pick it up. They both lost their penalties.
*And let's not forget the last moment save he did at 120+3' unbelievable!
In contrast France's Lloris was a disaster failing to stop at least one of 2 bad penalties (Messi, Dybala) or that one of Paredes.
Argentine deserved to win. They totally dominated the match for 80' and they demolished French in the centre by most of the time. And if Scaloni hadn't subbed Di Maria maybe we would be seeing a 3-0 final score instead.
