The Clay Master, Rafael Nadal is very much on course to win an astonishing 11th French Open title after a straight-sets win over Maximilian Marterer in Monday’s Round of 16 tie.

The world number one, red-hot favourite to win the Roland Garros crown yet again, faced his toughest test so far but still came through unscathed to reach the quarter-finals.

Nadal was broken in the opening game by his 22-year-old opponent but that proved only a minor blip, though, as the Spaniard secured two breaks of his own to take the first set.

A break in the first game of the second put Nadal on his way to a two-set lead as Marterer appeared to wilt.

Yet Marterer is clearly a fighter and he broke for 3-1 in the third, only for Nadal to hit straight back.

Nadal still needed a tie-break to see off a stubborn opponent - winning his 37th consecutive set at the tournament - for a 6-3 6-2 7-6 (7/4) victory.

He will be battling it out against Diego Schwartzman, the 11th seed, for a place in the semi final after the Argentinian pulled off a stunning fightback against Kevin Anderson.
