Simon was still smarting from an arduous five-setter with compatriot Gael Monfils in the previous round in a match which drifted into the early hours of Sunday morning.

Simon said he had "completely lost control" during the four hours and 43 minutes marathon in round three, and Murray breezed past him on Monday.

Murray's victory against the Frenchman came in one hour and 35 minutes.
