World number one Djokovic completed his first private stranglehold of all four Slams with victory at Roland Garros in 2016. Federer and Nadal, with 20 and 17 career Grand Slam titles each respectively, may be ahead of 15-time major winner Djokovic in total hauls and have also completed career Slams. "Nadal, number one favorite, without a doubt — then everyone else," he said. Thiem, the 2018 runner-up to Nadal at Roland Garros, has defeated the Spaniard four times on clay. Outside of Djokovic and Federer, world number four Thiem and sixth-ranked Tsitsipas are the most likely candidates to dethrone Nadal.
