Federer was the oldest man left in the field and would have been the oldest quarterfinalist in Australia since Ken Rosewall at 43 in 1977.
It was a disappointing performance from Federer's perspective, as he missed all 12 break point opportunities while making a total of 55 unforced errors. "I don't care how I do it, but I have to do it. Cost me the game tonight".
To his credit, Federer played down the controversy in his post-match press conference. It's not always easy, especially for younger guys. He had to stave off two break points to hold.

'I guess so. He has a one-handed backhand and I used to have long hair, so maybe a little bit, ' reflected Federer ruefully, when asked for similarities between his young self and his conqueror, also pointing to the Greek's old-school continental grip. "You're not going to get many chances against Roger, when you get them you have to take them". He's doing that. It's really nice for him. The two played against each other at the Hopman Cup team exhibition event two weeks ago but Federer acknowledges Sunday's match is "best of five, it being a fourth round of a Slam, you know, where we know now how we feel on this court". I like this aggressive game, coming into the net, and serve and volleying now again.
