Rafael Nadal romped to a record 11th Monte Carlo Masters Tennis title by brushing aside Kei Nishikori in final to retain the world number one ranking.

The 31-year-old saw off Nishikori in straight sets by 6-3 and 6-2 to become the first man to win a tournament 11 times in the open era with his 76th ATP tour triumph.

Nadal’s 31st masters title is also an outright record, pulling him out of a tie with Novak Djokovic.
