The quarter-final was rained off Friday night and delayed for two and a half hours by more poor weather.

The timing means that France’s 16th seeded Monfils had just a few hours to prepare to take on defending champion Nadal, who eased through on schedule, Friday.

Monfils admitted he may have limited chances against a player who has beaten him 14 times in 16 matches.

Monfils last beat the Spanish superstar seven years ago.

“There were so many delays, I’m really tired,” Monfils said after working for almost two and a half hours to advance.

“I know there is not much time until Rafa, I’ll have to speak with my team and see what I’m able to do.”

Monfils has come good this week after retiring due to an injury in the first round at Wimbledon.

The 32-year-old won the Rotterdam title earlier this season.

In the first semi-final, which started more than three hours later, Russian seeds Karen Khachanov and Daniil Medvedev were facing off for the third time in their careers, with the pair standing 1-1.
