Roger Federer, Serena Williams and Rafael Nadal on Saturday (16 January) discussed the 2016 Australian Open which starts on Monday (18 January).

SOUNDBITE (English) Roger Federer, third seed: (On his first round opponent Nikoloz Basilashvili)

"I don't know my opponent very well. I almost played him at Wimbledon, I remember. So we'll see how that goes. More focused on my own game right now. My health is good now, so that's crucial, especially now that I play on Monday. Yeah, so I'll get some feedback from Ivan and Severin, see what they can find out about him. But then I think important is going to be how I'm going to play."

SOUNDBITE (English) Serena Williams, top seed: (On her knee)

"It's actually really fine. I don't have any inflammation anymore. It's just that I just needed some time to get over that little hump. Like I said, I've been doing a lot of, lot of, lot of training leading up to this. But, yeah, I'm totally.... I don't think I would need surgery at all."

SOUNDBITE (English) Serena Williams, top seed: (On what she wants out of her 2016 season)

"Honestly, I don't have anything to prove. I have nothing to lose. I can only gain. That's kind of how I look at it right now."

SOUNDBITE (English) Rafael Nadal, fifth seed: (On the big four and Novak Djokovic's recent success)

"I really don't care much about it. Just the only thing that is true, is Novak is playing at better level than the rest of the players now. That's obvious, no? The way he's playing, it's difficult to see him losing matches. Just can congratulate him for made that happen."
