Novak Djokovic has drawn attention at this year’s Grand Slam tournaments by revealing a mysterious coin-shaped device tapped into his chest.

The tennis star displayed this device both during the French Open and Wimbledon, sparking speculation about its reappearance at the upcoming US Open.

Following his triumph over Marton Fucsovics in the second round of the French Open in May, the 23-time Grand Slam champion addressed the curious disk.

He labelled the discreet chest patch as the “most significant secret” of his career,

“That’s probably the biggest secret of my career. If it wasn’t for that, I probably wouldn’t be sitting here.” Said Djokovic

Following Djokovic’s comments, an Italian company called Tao Technologies said it was behind the device.

Termed as a “human enhancement device,” the Taopatch “uses two layers of nanocrystals that convert heat from your body into light.”

It also sends therapeutic signals to the wearer’s nervous system to help their body achieve true balance.

Reportedly, the benefits it offers encompass improved sleep quality, posture, balance, flexibility, recovery speed, and concentration.

Additionally, it is said to alleviate stress, anxiety, and persistent discomfort.

The company even asserts that the patch, starting at a price of £238, has shown efficacy in aiding individuals dealing with multiple sclerosis.

Novak Djokovic is poised to embark on his journey for a 24th Grand Slam singles title at the commencement of the U.S. Open.

The tournament’s onset finds Djokovic requiring only a triumph in the opening round to reclaim his position as the world’s number one player.
