Djokovic made a very compelling argument for that at the Australian Open where he cruised to another trophy and that was with an injured leg. A fully healthy Djokovic will certainly be tough to beat on any surface and Thiem, as many, consider him the meant to beat.
In a talk with Eurosport, Thiem discussed Djokovic together with fellow pro Casper Ruud who picked Nadal as the favourite for Roland Garros. They both agreed that both Djokovic and Nadal are still beatable though.
I have the feeling that there are many players now who can beat those two guys [Djokovic and Nadal]. There are great guys there, but obviously, also those two, three when Roger [Federer] was there, they were still one level above all the others, especially in the Slams, especially when it came to the best-of-five.
Like many tennis fans, Thiem would not mind seeing Djokovic and Nadal battle it out at the second grand slam of the year. They did so last year and Nadal won that match and the event in the end. Thiem could see that happening again.
For the whole tennis world it would be nice to see one last showdown in Roland-Garros, obviously, but Novak will still be the man to beat in the Grand Slams in 2023. The only tournament is Roland-Garros: if Rafael is fit there, it's exactly the opposite.
He's the man to beat, obviously, when he won the tournament 14 times, it's crazy. But if you see the performance of Novak at the Australian Open, which was incredible, he's going to be probably the favourite at Wimbledon and the US Open as well.
