Novak Djokovic and Roger Federer stayed on course for a mouth-watering French Open semi-final showdown on Sunday, but only after they survived fourth round scares at a chilly Roland Garros.

Djokovic staged an epic recovery to defeat Italy’s Andreas Seppi 4-6, 6-7 (5/7), 6-3, 7-5, 6-3 while Federer, the champion in 2009, dropped the first set against Belgian lucky loser David Goffin, the world number 109, before claiming a 5-7, 7-5, 6-2, 6-4 win.

World number one Victoria Azarenka crashed out.
