After his return from the USA, where he was eliminated in the early stages of the US Open, Novak Djokovic is back in Belgrade. He's using his free time to attend a Crvena Zvezda Meridianbet game, a team he's a passionate supporter of.

Upon entering Serbia's largest arena, Novak was greeted with thunderous ovations and applause. He then took his seat courtside with his father, Srđan, ready to cheer on the red and whites.
