The presence of these star forwards is viewed as a critical factor in the ability of Argentina and France to advance in the tournament [1]. Their participation drives high expectations for both squads as they begin their campaigns in the U.S.

France is scheduled to open its tournament run against Senegal on Monday, June 15, 2026 [2]. The match will take place at MetLife Stadium in New Jersey [2]. Mbappé, serving as the captain of the French side, remains a focal point of the team's offensive strategy [2].

Argentina will face Algeria in the first round of Group J [4]. That match is set to be played at Arrowhead Stadium in Kansas City [4]. Messi's role continues to be central to Argentina's ambitions of securing another title [1].

Analysts said that the health and form of these two players will dictate the momentum of their respective groups.
