Andy Murray: Yet to drop a set at this year's Australian Open
Andy Murray said it "would be silly" not to acknowledge his good form after making short work of Jeremy Chardy to reach the last four of the Australian Open.
The No 3 seed was never troubled on his way to a 6-4 6-1 6-2 success which booked a fourth straight semi-final in Melbourne - against Roger Federer.
Murray is yet to drop a set as he aims to become the first man in open-era tennis to follow up a first grand slam win with another.
And he said: "That was the best I have played. 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."
Two successive breaks of serve represented the good start Murray was after, and the world No 36 was always facing an uphill struggle to repeat his shock victory over Juan Martin del Potro earlier in the tournament.
"For me this was a decent test," Murray said. "I played a lot of tennis in December. I had some good lead-up matches in Brisbane. So I can't be disappointed about being in the semis of a slam without dropping a set. That would be silly.
"I think you have to trust yourself that when you are tested you're going to play better tennis. You never know for sure. But in the build-up to the tournament I played very well. I haven't lost a set here yet.
"I've done a good job so far in this tournament. I can't be disappointed with where my game's at and I hope the next round I play better again."
