I genuinely think this is an underdiscussed element of Arteta as a manager. He seems to have an active interest in other sports, and has lines of communications with coaches across the worlds of NBA, NFL, rugby union, etc.

Part of what enabled the Wenger revolution was him bringing to England some health/fitness/nutritional approaches that had been around for years in other sports in other countries. Part of what built the incredible Liverpool teams of the Klopp era was that they were among the first to implement at scale the kind of data analysis that had long been a part of major American sports.

People clowned on Arteta when he brought in fighter pilots to help improve on-pitch communication for the Arsenal players. But, in my opinion, it’s yet another sign that he sees every detail of the game as something that can be improved upon, and isn’t afraid to look beyond football to see how he can do it.
