Guardiola himself has previously spoken about studying tennis and basketball to understand how to improve his footballing teams.
"Incredible athletes, [Roger] Federer, [Novak] Djokovic, [Rafa] Nadal. The biggest dynasties in the NBA. It’s not easy in the NBA to have a team like the Chicago Bulls with [Michael] Jordan. I’m not comparing with that, don’t misunderstand me. The NBA has a lot of clubs with two or three in a row," he said earlier this year.
