Andy Murray preserved his immaculate record at the Australian Open as he defeated Jérémy Chardy in straight sets to reach the semi-final stage.

Murray had been expected to meet 2009 US Open champion Juan Martín del Potro in the Melbourne quarter-finals, but was largely untroubled as he beat Chardy 6-4 6-1 6-2 in one hour and 51 minutes. He will face either Roger Federer or Jo-Wilfried Tsonga in the last four.

"Today was the best I have played (in the tournament)," the Scot said. "I struggled in the last few rounds a little bit and my last opponent (Gilles Simon) was struggling physically so it wasn't much of a match. Jeremy has beaten some great players so I had to come out sharp."

He confirmed he would not be tuning in for the duration of the other quarter-final.

"I'll watch a little bit but not the whole match. I will get an early night and hope that Roger and Jo play for four or five hours!" the 25-year-old added.
