No extra Australian Open pressure for favourite Federer

Though his withdrawal from Doha was disappointing, Thiem will certainly be ready for the Australian Open. "Australians are always getting great support here. For now everything at the moment is going in the right direction", the Serbian star said on Thursday.

Austrian world No.5 Dominic Thiem insists he'll be fit for the start of the Australian Open as he recovers from a virus and jet-lag.

Here is the list of players who have been struggling with fitness in the lead-up to the first Grand Slam of the year.

"All these things all play into it but at the end of the day I've been in this position thankfully many times before".

"For now I'm in the tournament and let's hope with God's grace everything will be fine in the next five days".

"I remember it was a lovely place and ever since I fell in love with Australia."In a happy place physically, the 36-year-old Federer is also in a happy place mentally as he travels alongside wife Mirka, their twin daughters Myla and Charlene, as well as twin sons Leo and Lenny".

"Rafa and Roger are the best ones, but I'm playing well and I'm in good shape".

"Me and Safwat have been really good friends for a long time and a year ago we didn't play many tournaments together but we always try to support each other, help each other as much as we can, so it's a really good thing for me that I have him hear by my side and also that I'm there for him in his matches", says Maamoun.

Serena Williams, Andy Murray, Kei Nishikori and Victoria Azarenka are all big-name players who won't be participating in the Australian Open this year.

Nadal leads in their head-to-heads by 23 to 15, and in Grand Slams by nine to three. With Roger Federer the front runner in this year's tournament Down Under, the Swiss will be looking to equal this record since he is one AO slam short, something that Nole would like to prevent.

"Last year's season was a bit long and I had to start a little bit later than I would've liked".

However, perhaps the most significant indicator of who could shine brightest in 2018 came in October when Caroline Wozniacki battled to a maiden WTA Finals title, displaying a new brand of ruthless tennis that suggested a first grand slam was imminent.

Having not featured in a competitive match since he withdrew from the World Tour Finals in November with a knee injury, Nadal was clearly keen to shake off the rust before his first-round match against Dominican Victor Estrella Burgos.
