Dominic Thiem, a former top tennis player and 2020 US Open champion, is set to retire this week, reflecting on his career marked by significant achievements and challenges, particularly due to injuries. His fellow players, including Novak Djokovic, Rafael Nadal, and Roger Federer, have expressed their admiration and sorrow over his departure from the sport. Thiem acknowledged that winning a Grand Slam did not bring the lasting happiness he expected, stating, 'I thought it would make me happy forever, but it doesn’t.' He believes that the retirement of the Big Three will not simplify the pursuit of major titles for other players, as new talents like Jannik Sinner and Carlos Alcaraz have emerged. Thiem's journey was marred by a wrist injury that hindered his ability to compete at the highest level after his initial success. His final match will take place at the Vienna Open, marking the end of a notable chapter in his life and career.
