Angelique Kerber
Two quarter-final appearances in 11 main draw appearances at Roland-Garros might suggest the masterful German should struggle to complete her career Grand Slam but there’s no question she has the ammunition to become only the seventh woman to achieve the full set of major triumphs.
It is still the only Slam where she has not even reached the semi-finals - a stark contrast to the seven times that she has made the last-four in Melbourne, Wimbledon and New York - yet three clay-court titles represents evidence she can succeed in Paris.
“If I had the chance to complete the career Grand Slam, that would be amazing, but I'm not thinking about this,” protests the 31-year-old, who has suffered too many first-round exits at Roland-Garros - five - to get ahead of herself.
In the past, she’s often conceded that she has never felt that comfortable with her movement on the clay but she looked good here last year, losing a hard-fought three-setter to the eventual winner Simona Halep in the quarter-finals.
This year, she also thinks the big-match experience of her latest coach Rainer Schuettler, the last German man to reach a Grand Slam final at the Australian Open in 2003, can help give her a sharper edge.
Fabio Fognini
When it comes to Roland-Garros, the Italian has often flattered to deceive a little on the surface where he has won eight of his nine career titles. Yet there’s still the tantalising prospect this could be the year he eclipses his best performance here eight years ago when he was a quarter-finalist.
Yet why now should we be won over by the fanciful idea that the mercurial one has a Grand Slam in him? Well, first, there was his huge breakthrough Masters win in Monte Carlo, when he defeated Rafael Nadal, albeit a seriously out-of-sorts Nadal, en route.
Then there was the testimony of his wife Flavia Pennetta, the former US Open champion, who reckons the new father is now living “the best moment of his career” and even laughs that one of the sport’s most combustible figures now looks at peace on court.
Could the taming of Fognini be the making of him?
Ashleigh Barty
The affable 23-year-old Australian, who has risen to world No.8 after a splendid season, has a nice self-effacing line when it comes to the clay-court season. “Every week on clay is a week closer to the grass season,” she likes to laugh.
Except it now looks as if her ever-improving nous on clay is no laughing matter for her opponents. For while the modest Queenslander admits she still has a lot to learn about her game on the surface, even she’s seen enough of an improvement to declare: “I think I have the game on clay to be able to do some damage.”
She is not alone in thinking that, either. “I know it’s probably verbally not her favourite surface to talk about but she’s building on this surface and I think she has a game that completely suits it,” Australian Fed Cup captain Alicia Molik told tennismash.com.
With her effective kick serve and booming forehand, there are shades here of Sam Stosur, another Australian who thrived at Roland-Garros with her one final and three semi-final appearances.
Grigor Dimitrov
You might think it hard to make a case for the gifted Bulgarian at a venue where he has failed to get past the third round in eight attempts.
His former coach Patrick Mouratoglu observed how Dimitrov's weaker second serve kicker has meant he often struggles to make a big impression on clay and he certainly hasn’t made great waves at any of his recent four clay-court tournaments after missing Rotterdam, Acapulco and Indian Wells with a shoulder injury.
