Novak Djokovic began his preparations for the new season on Thursday with a 6-2, 4-6, 6-2 win over Gael Monfils at the World Tennis Championship exhibition event.

The No. 1-ranked Djokovic is coming off a 70-6 season in which he won three Grand Slam titles. The 24-year-old Serb ended his best ever season with two tired losses at the ATP World Tour Finals last month but got back to winning ways against the No. 16-ranked Monfils.

Djokovic will face Roger Federer in the semifinals on Friday when Rafael Nadal will meet fellow Spaniard David Ferrer.

Ferrer earlier beat Jo Wilfried Tsonga of France 2-6, 7-6 (5), 6-2 in the $250,000 winner-takes-all six-man championship.

Djokovic, who blamed fatigue for an early exit at the ATP Finals last month, said he was still not fully fit and probably needed another week or two to be match ready. But he said he has no plans to play any other warm-up tournaments ahead of the Australian Open which runs from January 16-29 - a strategy that served him well last season.
