Australian tennis star Nick Kyrgios and former tennis player Boris Becker got into a heated exchange on twitter with the tennis figures calling each other a rat and a doughnut. The battle started after Kyrgios posted a video on Instagram and criticized German tennis player Alexander Zverev for partying in Monaco with many people, despite promising to self-isolate after Novak Djokovic’s Adria Tour.

After Kyrgios called Zverev “selfish,” Djokovic’s former coach Becker described Kyrgios as a rat.

“Don’t like no #rats! Anybody telling off fellow sportsman/woman is no friend of mine. Look yourself in the mirror and think your better than us…” said Becker.

Kyrgios replied to the tweet by talking about how “idiotic” Zverev’s actions were. Becker answered to Kyrgios by calling him a rat again and unhappy with the insult, Kyrgios called Becker a doughnut and said, “Can hit a volley, obviously not the sharpest tool in the shed though,” mocking his decisions and comparing it to his tennis skills.

Becker then responded by calling out Kyrgios for never winning a Grand Slam.

“I would really like to see Nick Kyrgios fulfill his potential and win a Grand Slam! He would be an incredible role model for the youth of the world addressing the issues of equality/race/heritage! Man up buddy and deliver!” said Becker.

Kyrgios was not happy with the fact that Becker tried to shift the focus from their initial debate. Kyrgios finally replied by expressing his feeling on how Zverev should give an explanation to the community instead of a general and meaningless apology.

“Why are you now talking about tennis? It has nothing to do with tennis?” he replied. “How about the dude who you are defending mans up and gives us some sort of explanation? Not another average management apology.”

The Australian tennis player also shared his criticism about the rescheduled US open that is set to take place between August 24 and September 13. He called the people who are pushing the US Open to happen “selfish.”

Kyrgios, currently ranked number 40, has advanced to the quarterfinals in five Grand Slams, while Becker has six major trophies, two at Wimbledon, two at the Australian Open and one at the US Open, as well as an Olympic gold medal in doubles in 1992.

Novak Djokovic’s Adria Tour

The Adria Tour was an exhibition tennis tournament in Croatia and Serbia, organized by the number one ranked tennis player, Novak Djokovic, during the ATP Tour due to the coronavirus pandemic. Its purpose was to bring some of the world’s best players together and provide income for participants, as well as entertainment for the fans.

The event was called off after Djokovic tested positive for coronavirus. His wife, Jelena, tested positive, as well.

According to SportsCenter, it was reported that social distancing was non-existent, and there were no restrictions regarding physical contact during the exhibition matches. The 17-time Grand Slam Champion apologized through social media by saying “I am so deeply sorry our tournament has caused harm.

Many people criticized the superstar. Andrea Petkovic, world no. 87 female tennis player took the chance to compare the difference in behavior between men’s and female’s side of tennis with a post on social media criticizing Djokovic.

After the apology, a couple of people defended Djokovic, saying it was not his fault. Manchester United’s midfielder Nemanja Matic endorsed him by saying that Djokovic did not do anything wrong and just wanted to help out the community.

Serbian Prime Minister Ana Brnabic claimed that it was all her fault, and she is to blame for allowing such an incident to happen.
