Melbourne: Roger Federer says a 36-year-old should not really be considered a favourite for the Australian Open, although when the man in question is himself, no one was taking him seriously.

The Swiss breezed through his media duties on Sunday with the same swagger he will take on court against Slovenia's Aljaz Bedene on Tuesday, when he kicks off the defence of the title he won against great rival Rafa Nadal last year.

That unforgettable triumph ended a five-year hiatus in Federer's Grand Slam collection and a few months later, he took his tally to a record-extending 19 by winning Wimbledon.

Few would bet against him becoming only the fourth tennis player to reach 20 in two weeks time, although Federer was reluctant to accept the favourite's tag.

"With age, I feel like I play down my chances just because I don't think a 36-year-old should be a favourite of a tournament, it should not be the case," he told reporters.

"That's why I see things more relaxed, you know, at a later stage of my career."

Federer says the likes of six-time champion Novak Djokovic and Stan Wawrinka, both returning after lengthy injury breaks, could benefit from the same mindset he arrived with in Melbourne last year, when he was just back from a six-month hiatus.

"This year I hope to win the first few rounds and get rolling, whereas last year it was more of a 'let's see what happens' kind of tournament," Federer, who is seeded second behind world No. 1 Nadal, said.

"Maybe similar to what Novak or Stan or others are going through this year. It's like, let's just see what happens. If you're in the draw, you give yourself a chance.

"That's what happened for me last year. All ended up way better than I thought it would. Having no expectations was so nice after all these years always having expectations."

Despite being a year older Federer has higher expectations this year and says his build-up has been 'perfect'.

He won all his four singles matches as he and Belinda Bencic helped Switzerland lift the Hopman Cup in Perth.

"It was a great preparation last year. I think it's going to be helpful again for me this year because the court plays exactly the same in Perth and here in Melbourne," he said.

Federer is bidding to win successive Australian Opens for the first time since 2006-07.

Meanwhile, according to Boris Becker Australian maverick Nick Kyrgios is ready to win over his doubters and can become an 'international sporting superstar'.

The 22-year-old, ranked 17th in the world, won the Brisbane title in the build-up to his home Slam and Becker says the man who divides opinion like no other in Australia is finally beginning to look like the real deal.

"There has never been a question mark over his talent but there was a question mark about his discipline," Becker said. "But he's getting it together now. It would be wonderful to see him get to the quarters or semi-finals. He has a huge following and is slowly getting it together. It's great. I am a huge fan of Nick." Reuters
