Martinez may have been an unused substitute in the final, but he can still feel very proud of his contribution to his country's cause throughout the tournament.
The same can be said for his United team-mate Raphael Varane, who reportedly overcame the effects of an illness to start for the eventual runners-up and play until extra-time when he was replaced.
Kylian Mbappe’s hat-trick for Varane's side was enough to take the game to a penalty shootout. However, Kingsley Coman and Aurelien Tchouameni missed their spot kicks, before Gonzalo Montiel scored the winner to give Argentina their third World Cup overall and a coveted first one for their talisman, Lionel Messi.
