Australian Open: Andy Murray pleased with 'big step up' against Feliciano Lopez

Andy Murray describes his third round Australian Open win against 26th seed Feliciano Lopez as a 'big step up.'

Playing in blustery 20C conditions in the Hisense Arena, Murray was never in serious danger against Lopez, winning 7-6 (7-2) 6-4 6-2.

He now faces France's Stephane Robert in the last 16 - the first man ever to make the tournament's fourth round after losing in qualifying before getting a "lucky loser" place when another player withdrew.
