Venus Williams has targeted a consistent run of form having reached the quarter-final stage of a Grand Slam for the first time since 2010.

The 18th seed has endured a tough few years, although she appears to be reaching something close to her best following this morning's 6-3 2-6 6-1 victory over Agnieszka Radwanska.

Williams fell behind early on in the deciding set, before battling back to claim a huge win which will see her take on fellow American Madison Keys in the last eight of the competition.

Asked about her mentality in the closing stages, she said: "Honestly, I don't know. I just felt like in the third set I was trying to get back to the form that I was in in the first set.

"I didn't do a lot wrong in that first game. It was just overhit some, missed an easy one that would have definitely helped my cause. It was frustrating but I stayed focused and I wanted to just continue playing like I did in the first game because it was really the right way to play

"I think a year ago I had a lot more trouble with putting a lot of good points together. That comes with just being able to play, playing consistently. I think just being able to build that momentum up, play matches, start to play a lot of good points in a row has been a difference."

Williams's best finish at the Australian Open came back in 2003 when she reached the final.
