Roger Federer sits slumped in his chair, head bowed as he looks at the floor. Even he - the man who has been here 17 times before - can't comprehend what has just happened.
After six months out through injury, at the age of 35 years (and 174 days - that's important), he's only come back and cleaned up. If cheap Danish lagers made fairytale tennis stories...

Simply astonishing. Federer is in tears in the middle of the Rod Laver Arena. He's beaten two top five players and his nemesis over five sets. He has been winning these things since Wimbledon 2003.

It didn't reach the height of other matches but as far as drama, it ebbed and flowed. It was spectacular but the fifth set went to another level. None of us expected them in the final. There was just a little bit more zip in Federer's shots and that is what it took.

When you teach kids and people about rhythm, this is what we're talking about. That just flew off the racquet, perfectly well-timed.
