But what did Novak Djokovic's entourage want to hide in the stands during the final of the Rolex Paris Masters against Holger Rune on Sunday?
While the Serb was battling against the 19-year-old Dane, his clan, during a change of sides, prepared a drink that we imagine energizing.
A spectator captured the images of the staff preparing this mixture.
In this short sequence broadcast on social networks, we see a man rummaging through a bag, taking out a bottle of water and concocting the famous mixture.
But when one of the members of the Djokovic clan realizes that the scene is captured on video at the foot of the tribune, he warns his neighbors so that they position themselves in such a way as to hide the man busy with the drink.
Once the drink is ready, it is entrusted to a ball collector who hastens to give it to Djokovic.
This strange body language, which fuels suspicion as Djokovic quietly drank the drink in stride, challenges.
Each player has his own little tricks to ensure optimal hydration during matches.
Each player has their little tricks to ensure optimal hydration during matches.
We often see two bottles at the feet of the stars of the circuit during matches.
The first is often filled with water, intended for hydration while the second, energizing, generally contains carbohydrates and minerals (sodium, calcium, potassium and magnesium).
These elements allow good muscle contraction and relaxation but also ensure good nerve transmission.
At each change of side, the players alternate between a few sips of water and an energy drink.

Novak Djokovic, who adopted a very elaborate diet consisting of asking his body as little as possible to digest (quinoa, millet and wild rice, steamed or boiled sweet potato) had already attracted the attention of spectators during the tournament of Wimbledon 2022 during side changes.
The Serb had given the impression of inhaling the contents of a gourd, again fueling speculation on social networks.
The 21-time Grand Slam champion laughed at these questions by telling the media that it was a “magic potion”.
