Here are five players who the top guys will be hoping to avoid as they find their feet in the first week at Roland Garros:
By his standards, Tsonga is having a truly awful year, making just one final and a couple of quarter-finals in ten tournaments so far. Having been a regular fixture in the top ten for a few years, the lovable Frenchman risks sliding to the bottom end of the top 20 if he doesn't defend a good chunk of the points he holds for reaching the semi-finals last year. Still, on his day, big Jo is capable of some explosive tennis, and will be seeded to face one of Nadal, Djokovic, Wawrinka or Federer if he reaches the last 16. Let's hope Tsonga can draw some inspiration from somewhere and get back to the level that saw him reach the last four without dropping a set last year.
Fabio Fognini (Seeding: 14)
The last few months have been memorable for Fabio Fognini, but not for the right reasons. Altercations with umpire Mohamed Lahyani marred his appearances in Monte Carlo and Madrid, he pulled out of Barcelona having lost ten games with no response to Santiago Giraldo before proceeding to shake off whatever "injury" he was struggling with to play doubles for the remainder of the week, and he was unceremoniously dumped out in the first round of his home event in Rome last week by Lukas Rosol. The very definition of enigmatic, Fognini could lose to a qualifer in the first round of this year's French Open, but if he feels like it, he can be one of the toughest opponents to play on the red stuff, as Andy Murray found out to his peril earlier this year in the Davis Cup.
Ernests Gulbis (Seeding: 18)
Gulbis came into the French Open ranked 40th last year, but has won three titles since, including a success on French soil in Marseille this year, where he defeated Richard Gasquet and Jo-Wilfried Tsonga. With his unique playing style and explosive temper, the Latvian is one of the most entertaining players on tour, and at his best, packs a real punch. For whatever reason, Gulbis has a poor 20-26 career record in Grand Slam matches, but his best run did come here back in 2008, where it took Novak Djokovic to halt him at the quarter-final stage. Keep your eye on this guy.
Alexandr Dolgopolov (Seeding: 20)
'The Dog' has disappeared under the radar a bit since his impressive runs at Acapulco, Indian Wells and Miami saw him surge up the world rankings, so given his poor performances since the clay swing got underway in Monte Carlo last month, the Ukrainian may be somewhat of a surprise inclusion here. However, Dolgopolov defeated Almagro, Fognini and Ferrer en route to the Rio de Janeiro final in February to underline his credentials on this surface and has since taken wins over Nadal, Raonic and Wawrinka too. The lack of momentum he carries into the French Open this year may be a concern, but don't expect The Dog to roll over if he's faced with a big name at some point.
Gael Monfils (Seeding: 23)
Monfils returned to the tour in style last year, reaching the final in Nice before making the most of his wildcard entry into Roland Garros, upsetting Tomas Berdych in the first round. 'La Monf' is a big hitter from the back of the court, loves to slide around on the clay, and with the backing of the French crowd, is capable of giving some of the top seeds something to think about. It took Roger Federer to halt La Monf's progress at Roland Garros when he reached the semi-finals in 2008, and the quarter-finals in 2009 and 2011, so the Frenchman has pedigree at this event. Let's just hope he decides to concentrate, and hope even harder that he doesn't pick up an injury while competing in Nice this week.
