Potential surprise packets - ATP

GRIGOR DIMITROV (BULDimitrov has long been touted as a star of the future, and he has followed up an impressive 2014 with a strong start to the year. The Bulgarian's style of play enables him to perform well on every surface while making it all look effortless - earning comparisons with 17-time grand slam winner Roger Federer. Clay has not always been his favoured surface, though, so he will be hoping to build on his good form on the dirt this season in Paris. He reached the quarter-finals in Monte Carlo and Madrid earlier this year, and went one better at the Istanbul Open. A favourable draw could help the world number 11 go far at Roland Garros.

FABIO FOGNINI (ITA)Capable of the sublime and ridiculous, it can be hard to predict just what you are going to get from Fognini but, on his day he can trouble the best - just ask Rafael Nadal. The 'King of Clay' has lost twice to the Italian on the dirt this year, including a straight-sets defeat in Barcelona. That match saw the best of Fognini - aggressive in his play, accurate on his serve and in control of his emotions. If he can find a similar mood in Paris he could be a threat to the top seeds. Clay has given Fognini his best moments on tour with all three of his titles coming on the surface, and he also reached the last eight at Roland Garros in 2011 - his best grand slam performance.

DAVID GOFFIN (BEL)Belgian tennis has produced some fine clay-court players in the women's game with the likes of Justine Henin and Kim Clijsters, and now Goffin is leading the way for the men. With a dangerous double-handed backhand, the 24-year-old is becoming a regular in the latter stages of competitions, the most recent being a quarter-final appearance in Rome. A battling display against David Ferrer in the last eight emphasised his growing confidence on tour, and that could cause problems for some of the more established players in Paris. Goffin has risen to a career-best 18 in the world in 2015 thanks to victories over the likes of Jo-Wilfried Tsonga and Ernests Gulbis.

NICK KYRGIOS (AUS)After announcing himself to the tennis world by beating then-world number one Nadal at Wimbledon last year, Kyrgios has established himself as a dangerous opponent on the tour and he beat Federer in Madrid earlier this month. The Australian has performed well on clay thanks to his athleticism and big serve, helping him to the final in Estoril and victory over Federer. While he may only be ranked world number 30, the 20-year-old tends to save his best form for the big events, reaching the quarter-final at the Australian Open after his exploits at Wimbledon. He struggled at the French Open last year, but his current form on clay should stand him in good stead this time around.

BORNA CORIC (CRO)One of the up-and-coming stars on the ATP Tour who has the potential to surprise at Roland Garros, as Andy Murray well knows after Coric beat him in Dubai earlier this year. It might be too much to expect the 18-year-old to go far in his debut at the French Open, but nothing fazes the youngster and his performances in the junior competition - when he reached the semi-final in 2013 - should give him confidence of making an impact. The Croat is rated highly within the sport, and was named 'star of tomorrow' by the ATP in November 2014.
