When Rafael Nadal and Roger Federer square off overnight in the men's semifinals at Roland Garros, it will be their 39th career meeting.
The Spaniard has won 23 matches to 15, with 12 of those wins on clay to Federer's two on the surface. However, Federer has won their last five matches with the last time they met coming in Shanghai in October 2017.
Nadal is gunning for a 12th Roland Garros title. He has lost here just twice since 2005 with his record standing at 91 wins and 2 defeats. Only twice has he been pushed to five sets in Paris. It would seem like mission impossible for Federer who lost the 2007, 2008, 2010 and 2011 finals to Nadal at Roland Garros along with the semifinal in 2006. Surely in 2019, Federer who turns 38 in August and hadn't played on clay since 2015 prior to his return in Madrid last month, doesn't stand a chance against the King of Clay?
There is a school of thought going around that Federer actually has the best chance he's ever had of dethroning Rafa. Craig O'Shannessy is a leading tennis strategy analyst who does work for the ATP Tour, grand slams and is part of world number one Novak Djokovic's wider team.
