Leandro Trossard joined Brighton in 2019 and spent four seasons with the Seagulls before switching to Arsenal in January 2023 in a deal worth up to £27m. At moments last season he looked ludicrously talented, beating players with his low centre of gravity and superb dribbling skills. "That's the story of his whole career - you don't think he will reach the next level but he hits the top every time," said Bocholter's current goalkeeper Stijn Wertelaers, Trossard's former team-mate and friend.
