Nick Lester - French Open Semi-Finals Preview
We reach the semi-finals of this year's French Open and the tie of the round is undoubtedly the clash between the two best clay court players of their generation, Rafael Nadal and Novak Djokovic.
On the other half of the draw, conquerer of Roger Federer, Jo-Wilfried Tsonga, takes on the in-form David Ferrer and with both players yet to drop a set, something has to give.
On the Women's side, reigning Champion Maria Sharapova takes on first-time semi-finalist at Roland Garros, Victoria Azarenka, and hot favourite Serena Williams plays last year's runner-up Sara Errani.
Sky Sports' Nick Lester joins Mark Walton to look ahead to the four semi-finals, giving us his best bets in each and telling us who expects to reach the final in both the Men's and Women's draws.
