Karen Khachanov should have been worried as soon as he stepped onto court with Novak Djokovic at just before 7pm last night.

Djokovic is never more dangerous than when on the receiving end of a perceived slight, and two days on from feeding off the Centre Court crowd’s baiting to defeat Kyle Edmund, he now had the Wimbledon schedulers in his sights.

Djokovic’s slot of third on Court No 1 to face Khachanov meant that for the second successive year he was facing the likely prospect of not finishing his fourth round on "Manic Monday".

Last year Djokovic was left furious after his last-16 match against Adrian Mannarino was held over until the Tuesday, contributing to his retirement against Tomas Berdych a day later.

But with the light fading and the wind billowing around the players yesterday, Djokovic set about his business with ruthless efficiency.
