For two weeks every January thousands of people descend on Melbourne to watch young men and women stand on a rubber surface and hit balls to each other. Melbourne, January, tennis. It's the holy trinity of summer sport.
Like the Melbourne Cup, the Boxing Day Test and the Aussie Rules grand final, the Australian Open is an institution that transfixes the nation. In homes and pubs across the country, big screens and small, we are glued to the daily battles.
The city itself sizzles with an electricity that is absent from London, Paris and New York when they host Wimbledon, the French and US Opens. Unlike those Grand Slam events, the Australian Open is held in the centre of the city. Everywhere you look, people are going to, coming from or talking about tennis.
The buses and trams are chock full of fans who make the daily trek to Melbourne Park, a stone's throw from the MCG. On the way, they pass locals who pack Federation Square to meet, drink and watch the action on huge screens. The city is united with a sense of kinship that brings people back year after year.

It demands versatility, rewards soft touch as well as raw power, and requires a mental toughness that separates the best from the good. For many years this package was encapsulated in Roger Federer, whose artistry has made him the most magical player of all time, even if the jury is still out over whether he is the greatest.
Last year Federer had the strokes and the skill to beat Rafael Nadal in their final, but having lost to the Spaniard at Wimbledon
