World No 1 cites fitness, confidence as keys to his success

Novak Djokovic, entering the 141st week of his career at No 1 in the world and fresh off a milestone fifth Miami Masters title, just wants to keep up the pace as long as he can.

"I'm trying to enjoy the moment and also utilize this time of my career. I'm feeling confident and physically fit," Djokovic said after Sunday's gritty three-set triumph over Andy Murray in the Miami final.
