Andrea Berta is a heavy hitter in football management. He spent 12 years at Atletico Madrid, climbing from technical director to sporting director, and played a big role in their success—two La Liga titles, a Europa League, and two Champions League finals. He’s known for big transfers like Antoine Griezmann and Rodri, and his last summer window saw Atletico spend £180m on players like Julian Alvarez. Now he’s set to replace Edu at Arsenal.
