Video - Rinderknech and Vacherot train together before their final at the Shanghai Masters 1000

Inseparable, Rinderknech and Vacherot exchanged a few balls together before meeting again for the grand final in Shanghai.

This Sunday, it's time for the grand final of the Shanghai Masters 1000 between Arthur Rinderknech and Valentin Vacherot. Behind the poster of this completely unexpected final actually lies a true family fairy tale, as the Frenchman and the Monegasque are cousins and have supported each other throughout the tournament.

Today, the two men, ranked outside the top 50, will compete for the title of a prestigious tournament. Rinderknech and Vacherot have known each other inside out since childhood, and even embraced on the court after Rinderknech's qualification at the expense of Daniil Medvedev in the semifinals.

That's not all, as just hours before their showdown for the title, the two cousins trained together, to share this completely crazy common adventure to the very end (see video below).

"Things we don't see in every final, the finalists train together. But then again, not every final is contested between two cousins," wrote the official X (formerly Twitter) account of the Rolex Shanghai Masters in recent hours.
