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 8-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 start with a player who has the world at his feet. Winning two Grand Slams in 2019 – the Australian Open and Wimbledon – the Serbian finished the year behind only Rafael Nadal in the world rankings. Djokovic’s record in this decade, however, is unparalleled. The Serb has 15 Grand Slam titles since the start of 2010 – achieving his first just before the start of this decade – and is the man to beat in the betting markets next year. Only Rafael Nadal at the French Open is a favourite other than Djokovic. The bookmakers are clearly as scared of him as his opponents are.
