The sport of tennis is set for a defining season in 2020. With the top three players in the world over the past 15 years – Rafael Nadal, Novak Djokovic and Roger Federer – entering the twilight of their careers, new players have emerged as genuine threats to their supremacy.

In this eight-part series, we’ll assess each player in the top eight and what they can achieve in 2020. We’ll look at how their positions are under threat and what they can do to attain their goals in the season to come. It’s never easy to look forward, but with our 2020 vision, you’ll have the benefit of hindsight when you’re talking tennis during the next 12 months.

We continue our series with a look at Dominic Thiem, whose improvement in 2019 has seen him push the best in the game so close for titles that he is frequently discussed in the same bracket as Djokovic, Nadal and Federer. While it’s not yet fair to say that the four men should be seen as equal, could 2020 be the year that Thiem finally takes home a Grand Slam trophy?

The hard-hitting baseliner is determined to make the next year his year and has been close to glory half a dozen times in his career. Can he break through to win the Australian, French or U.S. Open? Could the awesome Austrian win Wimbledon?
