Rafael Nadal and Simona Halep will defend their French Open titles at Roland Garros, where play gets under way on Sunday.
World number one duo Novak Djokovic and Naomi Osaka will both bid to extend their winning runs at grand slams while Roger Federer returns to the Paris clay for the first time in four years.
Here, Press Association Sport picks out 10 other players who could make headlines.
Kiki Bertens
Kvitova has been the most prolific title winner on the WTA Tour over the past two seasons and reached her first grand slam final for five years at the Australian Open. A tough loss saw Osaka hit top spot in the rankings instead but Kvitova is now among the favourites on every surface.
Serena Williams
Williams’ build-up would suggest she is unlikely to last long in the city she considers her second home but she has proved many times she can turn it on at the grand slams. A knee problem that has curtailed her reduced schedule even further is a concern. The 37-year-old won the last of her three French Open titles in 2015.
Marketa Vondrousova
Austrian Thiem is seen as the heir to Nadal’s throne as the king of clay and reached his first slam final in Paris last summer. He was well beaten by the Spaniard on that day but defeated him on clay for the fourth successive season in Barcelona last month and went on to win the title.
Stefanos Tsitsipas
The young Greek’s run to the Australian Open semi-finals, beating Federer, cemented his status as a superstar in the making. The 20-year-old was shattered by the manner of his defeat by Nadal in the last four but turned the tables superbly when they met on clay in Madrid earlier this month. Fully believes he is ready to win a slam.
Fabio Fognini
Not an easy name to remember, but definitely not one to forget. The breakthrough star of 2019 on the men’s side has undoubtedly been the 18-year-old Canadian, who will be seeded at Roland Garros. This year is probably too soon for him to make a big impact at the slams but he has already reached a clay-court final in Rio as well as the semi-finals in Miami.
Cristian Garin
A new name on the ATP Tour, Garin will be one to avoid in the draw given his form on clay this season. The 22-year-old is the only player outside the top 10 to have won two titles in 2019. He will be making his main draw debut at Roland Garros but won the junior title in 2013, beating Borna Coric and Alexander Zverev.
