Background

Estêvão Willian is an 18-year-old winger who plays for Chelsea and the Brazil national team. He made his senior international debut for Brazil in September 2024. As of April 2026, his participation in the upcoming World Cup is uncertain due to a grade four hamstring injury sustained during a Premier League match against Manchester United on April 18, 2026. While he has been a consistent contributor for the national team throughout the qualification process, his final inclusion in the tournament squad depends on his recovery and selection by head coach Carlo Ancelotti.
