For the 2018 FIFA World Cup, Deschamps "was careful in selecting his 23-man roster for Russia, selecting only players who he felt could gel as a cohesive unit", resulting in the omission of Real Madrid’s Karim Benzema. Although initially criticized for conservative tactics as the national team had indifferent showings to advance from the group stage with narrow wins over Australia and Peru and a draw against Denmark, they put in dominant performances during the knockout rounds, defeating Argentina 4–3 in the Round of 16 and Uruguay 2–0 in the quarter-finals to reach the semi-finals. During the tournament, Deschamps also deployed Blaise Matuidi – normally a holding midfielder – out of position, playing him out wide, rather than in the centre, as a left-sided winger or attacking midfielder in a 4–2–3–1 formation. In this system, Matuidi proved to be equally effective, in spite of his unorthodox playing role, as he was able to track back and limit the attacking threat of the opposing full-backs on the flank. Moreover, he also often tucked into the centre, in order to help support Paul Pogba and N'Golo Kanté defensively, which also helped minimise the amount of space given to the main playmakers of France's opponents throughout the tournament, and ultimately helped to nullify their impact on the game in midfield. Furthermore, Matuidi's more defensive role on the left flank provided balance within the team, as it in turn gave Kylian Mbappé the licence to attack and run at defences from the right wing. Following these matches, France became World Cup winners after beating Belgium 1–0 in the semi-final and Croatia 4–2 in the final. As such, Deschamps became only the third man after Mário Zagallo and Franz Beckenbauer to win the World Cup as both a player and a manager, and only the second captain after Beckenbauer to do so.
