Manchester City defender Aymeric Laporte believes he's worked with the two best managers in the world.
Laporte joined City for a then club-record £57m in January 2018 from Spanish side Athletic Bilbao.
During his time with the Basque club he played under now Championship-leading Leeds boss Marcelo Bielsa - a manager whose influence on his career he has come to appreciate more over time.
“Looking back now is different to how it was then," admitted Laporte to BBC Sport. “When I was working with him it was so difficult. It was training every day, maybe some times two times a day.
“It was difficult to think, to have time for us. But now I know I improved a lot with him and he helped me to improve."
He also sees the influence Bielsa has had on his current boss Pep Guardiola, who has called the Argentine the best coach in the world.
“They are maybe two best managers in the world," he added. “Different managers, but they know everything about football."
