Roger Federer had some low expectations from himself before the Australian Open, as he had said that a 36-year-old shouldn't be the favourite to win a Grand Slam title. Although he ended up defending his trophy, the Swiss prefers to stay humble.

'I’m not sure how much I really felt like I could defend it. Maybe next year when I do come back I might actually believe I can win it. But then I probably won’t win it,' Federer stressed, as quoted by Eurosport, during his post-match photo shoot at the Australian Open, on Monday, 29th January.

Federer is yet to hit the practice court. 'I’m just very excited that I have nothing going on in the next couple of weeks. It’s all quiet so I can just take time to celebrate. Number 20 is super special so we’ll try to make the most of it.

It’s one of the great moments in my career. I’m still a little bit confused that it’s all over and that I was able to do it. It’s just a lot trying to take it in. Last year it was more straightforward, just disbelief, this year it seems more surreal. I can’t believe I was able to defend my title after all these years.'
