Novak Djokovic has a huge estimated net worth, built through prize money, endorsements and business ventures

Novak Djokovic will continue his pursuit of a record-breaking 25th Grand Slam title on Tuesday, when he faces Felix Auger-Aliassime at Wimbledon. The 39-year-old stands as the most decorated male tennis player in history, having cemented a legendary reputation in the sport and amassing seven Wimbledon titles amongst his extraordinary collection of honours.

To this day, he remains the only man in the history of the game to have held all four major titles simultaneously across three different surfaces. It comes as little surprise, then, that Djokovic's extraordinary on-court achievements have made him tennis' biggest financial earner.

Over the last two decades, he has accumulated a staggering $193.5million (£144.8m) in prize money alone, and could add a further £3.6 million to that figure should he secure his eighth title at SW19 later this month.

Djokovic's net worth - estimated to be in the region of $250m (£187m) - is further bolstered by a string of highly lucrative endorsement and sponsorship arrangements.

He has struck deals with tennis brands including Asics and Head, while away from the court, he has collaborated with the likes of Hublot, Lacoste and Peugeot.

The Serbian superstar has also joined forces with Lemero, NetJets, Raiffeisen Bank International and Ultimate Software Group throughout his career.

Djokovic shares his vast personal wealth with his wife Jelena, having first met at secondary school in Serbia before beginning their relationship in 2005. The couple tied the knot nine years later at a luxurious hotel resort in Montenegro and are now proud parents to two children - Stefan, 11, and Tara, eight.

Jelena is a savvy businesswoman and global CEO of the Novak Djokovic Foundation (NDF), a charity she co-founded alongside her husband, which aims to provide equal access to early childhood education.

She is a familiar face cheering on her husband from the stands at major tournaments and has never shied away from speaking her mind on incidents both on and off the court.

Earlier this year, she publicly took aim at women's singles star Naomi Osaka over her behaviour during her victory against Sorana Cirstea at the Australian Open.

A heated match saw Cirstea become increasingly irritated by Osaka's conduct between her first and second serves, particularly her habit of shouting 'come on' to fire herself up. This sparked a frosty exchange between the two players at the net when the match concluded.

At the time, Osaka - who is also competing at Wimbledon on Tuesday - delivered a combative post-match interview before subsequently apologising for her on-court remarks.

Nevertheless, Jelena wasted no time wading into the controversy, blasting Osaka for her "disrespectful" behaviour and taking to Instagram to voice her displeasure.

"Hm, I'm surprised that this is not being called hindrance," she wrote. "In between two serves, when crowds are applauding or shouting, the chair ump asks not to shout between serves as it is disturbing to the player.

"The point is not finished. Sorana missed her first serve and is focusing on getting in the second, it is a slight pause. And it is disrespectful to applaud at someone's first serve mistake too."

Taking aim at the officiating, she went on to say: "I am surprised that the chair / Naomi thought that was fair? ! Were there any rule changes that I missed?!"
