Video - Jannik Sinner's training session with Joao Sousa

Jannik Sinner will face his great rival Carlos Alcaraz this Sunday in the final of the ATP Finals. He was able to train with Joao Sousa, a former world No. 28 who has been retired since April 2024.

The Portuguese now works for the ATP in a role as a facilitator between the players and the ATP, with the goal of improving the players' daily lives.

But this week, Sousa picked up his racket again to serve as a sparring partner for the semi-finalists and finalists of the ATP Finals.
