Thiem, Zverev aiming to upset old guard at French Open

The French federation then refused to award Maria Sharapova a wild card for the tournament with the Russian on the comeback trail following a 15-month doping suspension.

Agassi, an eight-time Major victor and 1999 Roland Garros champion, retired from tennis after the 2006 US Open and has never coached professionally.

He'll need to come through some tough matches to reach the same stage again with Olympic final opponent Juan Martin Del Potro and former French Open victor Stan Wawrinka among the potential rivals on his side of the draw.

Djokovic and Nadal could meet in a mouthwatering semifinal showdown at the French Open. Agassi won eight major titles - four fewer than Djokovic - but has never coached.

According to Sky Sports, Agassi recently said that he turned Djokovic down when Nole first called about the job. I won a lot of matches.

Rafael Nadal insisted he didn't care if he was regarded as the favourite for a 10th French Open, even if his rivals begged to differ.

- Only three players have won the tournament without losing a single set: Ilie Nastase (1973), Borg (1978 and 1980), and Nadal (2008 and 2010). That will be followed by No. 1-seeded Angelique Kerber against Ekaterina Makarova.

Nadal's first title of 2017 came on the familiar Monte Carlo clay courts for the 10th time and there is no debate that he is a different player than the one we have seen in the last couple of years, which only bodes well for his run on clay.

"I need to recognize that scheduling will be the key to my longevity, thus, my team and I concluded that playing just one event on clay was not in the best interest of my tennis and physical preparation for the remainder of the season", Federer said. He already won the 2017 Australian Open in he's playing at such a high level this late in his career. Without them, there is no clear favorite to take the title. Can Halep land her major? 1-5 in the ATP rankings are all 30 or older for the first time in history.

But in what has been as astonishing "retro" year for men's tennis Nadal, with fellow Mallorcan Carlos Moya added to his coaching support, came within a whisker of beating Federer in an epic Australian Open final.

On the way to a possible semi-final with the 2015 champion Stan Wawrinka, the top seed could expect number 13 seed Tomas Berdych, German youngster Alexander Zverev or Japanese Kei Nishikori ahead.

Two-time Wimbledon champion Petra Kvitova will make her return to action Sunday at Roland Garros, less than six months after being stabbed during an attack at home in the Czech Republic.

Djokovic has himself admitted that he has been experiencing "a little bit of a crisis" since winning his first French Open title in 2016 to become the first male player to simultaneously hold all four grand slam titles since Rod Laver in 1969. He can also play unbelievable here. Nadal beat Novak Djokovic in 2012 and 2014, while Djokovic got the better of Andy Murray in last year's showpiece. An entire day of play was washed out, the first time that happened at the event in 16 years, and other weather-related decisions by tournament officials drew criticism from players.
