Andy Murray sailed into the quarter finals at the Australian Open on the weekend after crushing opponent Jurgen Melzer.

Murray dropped just five games as he steamrolled Austrian Jurgen Melzer, 6-3, 6-1, 6-1 in an hour and 44 minutes on Rod Laver Arena.

Tennis pundits are predicting that the Australian Open could be his for the taking given that potential semi-final opponents Rafael Nadal is under the weather with a cold and Roger Federer is having a rocky tournament.

But the fifth seed who is yet to win a grand slam isn’t about to rest on his laurels just yet.

"I feel good but the matches are definitely going to get tougher," Murray said post-game.

"I'm not expecting to go through the tournament winning matches like that, with that scoreline. So I'm ready for that mentally when it does get tough."

The British player now faces unseeded Ukrainian Alexandr Dolgopolov who has so far caused the upset of the Australia Open tournament by dismantling fourth seed, Robin Soderling.

Murray played Dolgopolov four years ago at the Davis Cup in Ukraine, defeating him in three sets.

"He's got a very unorthodox game," Murray said, "very different to most of the guys on the tour. He's starting to put everything together, taking chances.”

"He has a game that can make you play strange shots, so you need to play as solid as you can against him.”
