France's Olympic campaign is off to a strong start with both the men's basketball and rugby sevens teams securing important victories. Victor Wembanyama led the basketball team to a 78-66 win over Brazil, contributing 19 points and showcasing his talent as the NBA's rookie of the year. In rugby sevens, Antoine Dupont came off the bench to score a pivotal try, helping France defeat Argentina 26-14 and advance to the semi-finals against South Africa. Meanwhile, the U.S. men's soccer team impressed with a 4-1 victory over New Zealand, and France's soccer team secured a narrow 1-0 win against Guinea. Spain and Argentina also recorded wins, with Argentina recovering from an earlier loss to move to the top of their group. Tensions between France and Argentina have marred the atmosphere, particularly in rugby, due to recent incidents involving racist chants and other controversies.
