Gabriel dos Santos Magalhães (born 19 December 1997) is a Brazilian professional footballer who plays as a centre-back for Premier League club Arsenal and the Brazil national team. Known for his aerial dominance, aggression, and left-footed distribution, he formed the best defensive partnership in world football alongside William Saliba between 2023 and 2026. Gabriel's career at Arsenal began with instability but evolved into dominance. He became the highest-scoring defender in the Premier League over a three-season period, leveraging his height for set-pieces. By 2026, he was an undisputed starter for Brazil, displacing Marquinhos, and a vice-captain at Arsenal, celebrated for his passion and defensive "dark arts."
