Mario Hermoso is a Spanish centre-back who began his professional career at Real Madrid Castilla before moving to Espanyol, where he established himself as a reliable defender. In 2019, he joined Atlético Madrid, winning the La Liga title in the 2020-21 season. After a stint with Atlético, he moved to AS Roma in 2024, continuing his career in Serie A.
Hermoso is a left-footed centre-back known for his strong aerial ability and composure on the ball, allowing him to build play from the back. He is comfortable in a back three or four, using his positioning and reading of the game to intercept passes. His main weakness is a lack of top-end pace, which can be exposed against fast attackers.
