Two-time grand slam winner Garbine Muguruza is racing to recover from a thigh injury with just three days to go before she launches her Australian Open campaign.
The reigning Wimbledon champion's preparations were thrown into disarray when injuries forced her to withdraw from both of her lead-up events on Australian soil.
Muguruza retired hurt in the second round of the Brisbane International after suffering debilitating leg cramps.
She then pulled out of her Sydney International quarter-final against Daria Gavrilova with a right thigh complaint.
The world No.3 remains a top contender in a wide open field but has conceded she isn't 100 per cent fit ahead of Tuesday's opening clash with French wildcard Jessika Ponchet.
"I'm trying to be fully ready to go," Muguruza said on Saturday.
"Honestly, I never feel I'm super perfect in any tournament. It's true, when you have the grand slam, you even want to feel more ready.
"That's what I'm going through. I'm trying to every day improve, try to recover. I know I'm playing on Tuesday, so we'll see."
The reigning WTA player of the year, Muguruza was one of five to have claimed the women's world No.1 ranking last year, sitting atop the throne for four weeks.
Her injury struggles are particularly ill-timed considering she stands to benefit from superstars Serena Williams, Victoria Azarenka and Svetlana Kuznetsova withdrawing from the Australian Open.
But the Spaniard is refusing to let that bring her down as she looks to improve upon last year's quarter-final defeat to CoCo Vandeweghe.
"The feeling is excited because, you know, grand slams are the most important tournaments," she said.
"Of course, I will be happier if I would come here playing more matches. But that's not going to put me down at all.
"I'm looking forward to start. I have good memories from last year. In general, I always have good memories from Australian Open."
