The friendship between Carlos Alcaraz and Jannik Sinner: a children's game, a stage together and an Indian Wells final at stake. On April 2, 2019, a 15-year-old Spaniard made his ATP debut as a guest in the Alicante challenger.
They struck up a friendship that still lasts today, despite the fact that the two argue at the top of tennis. Last Christmas, in fact, Sinner was in Villena in another sign of his closeness.
