Gael Monfils complains of heat-stroke in Novak Djokovic loss

Novak Djokovic believes players were asked to push their physical limits at the Australian Open on Thursday after opponent Gael Monfils complained of suffering heat-stroke.

The thermometer edged towards 40C in the shade as Djokovic and Monfils took to a sun-baked Rod Laver Arena for their second-round match, which the six-time champion eventually won 4-6 6-3 6-1 6-3.
