Damián Emiliano Martínez (born 2 September 1992), known as "Dibu," is an Argentine professional footballer who plays as a goalkeeper for Premier League club Aston Villa and the Argentina national team. He is widely recognized as the best "big-game" goalkeeper in the world. After spending a decade as a reserve at Arsenal, his career exploded in 2020. He was the hero of Argentina's 2022 World Cup victory, making a legendary last-minute save against Randal Kolo Muani and saving penalties in the shootout. By 2026, Martínez had established himself as an Aston Villa legend, captaining the club in the UEFA Champions League. He won the Yashin Trophy back-to-back (2023, 2024), cementing his status as the world's number one. His psychological warfare during penalty shootouts has revolutionized the art of goalkeeping, though it has drawn ire from opponents and authorities.
