Insatiable Djokovic intensifies history quest

Novak vows 'to focus attention and energy' on catching Federer, Nadal

It didn't take long for Novak Djokovic to make his intentions clear: All that matters to him from here on out is catching Roger Federer and Rafael Nadal in the Grand Slam standings.

Forget about winning other, run-of-the-mill tournaments or playing enough to retain the No 1 ranking.

There is one, primary goal for the 33-year-old from Serbia. He wants to keep adding to his 18 major championships－he reached that number with his ninth Australian Open title on Sunday－until he no longer trails Federer and Nadal, who share the men's record of 20.
