⚽ Correct! Just Fontaine set the record for most goals in a single World Cup tournament by scoring 13 goals for France in the 1958 World Cup held in Sweden. What makes this achievement even more remarkable is that Fontaine accomplished it in just six matches. His scoring spree remains unmatched to this day. Fontaine wasn’t initially even France’s starting striker but stepped up due to an injury to the regular starter. His clinical finishing and sense of positioning made him unstoppable. Though his international career was short-lived due to injuries, his 1958 performance stands as one of the greatest individual campaigns in World Cup history. No player has come close to matching his single-tournament output, making Just Fontaine the correct answer here.
