Sarr shared his childhood dream of becoming the world's best centre back, inspired by players like Virgil van Dijk. He admires Van Dijk's leadership qualities and strives to develop similar skills. Some people compare Sarr's playing style to Ibrahima Konate, another skilled defender.

Before joining Chelsea, Sarr played for Strasbourg, which he moved to from Lyon just a year ago. He was aware of Chelsea's interest in him since November or December and had a feeling that a transfer might happen in January.

During negotiations with Chelsea's directors, Sarr was encouraged to focus on progressing and working hard. He understands the importance of training well, communicating with the coach and teammates, and being confident in his abilities.
