At 33, Nicolas Tagliafico approaches the 2026 World Cup as one of the most experienced members of Argentina's defending champions. The Lyon left-back played a key role in the Qatar triumph and also featured at Russia 2018. Combining technical quality with defensive discipline, Tagliafico has become an important part of Lionel Scaloni's system. In Qatar, he started two of the team's most decisive matches: the semi-final against Croatia and the final against France.

Argentina, competing in Group J against Algeria, Austria, and Jordan, will defend their crown for the third time in their history. In an interview with FIFA, Tagliafico discussed the challenges of defending the title, describing it as something very special and unique, knowing that everyone will want to beat them.

Reflecting on Qatar, he said the final stands out, but so does the defeat to Saudi Arabia. These were two completely opposite moments: one very high and one very low. Tagliafico also discussed his development as a player and the lasting impact of winning the World Cup, noting that the experience changed his perspective and gave him confidence that carries through to every match.
