LONDON: Novak Djokovic crushed David Goffin 6-1, 6-2 at the ATP Tour Finals on Thursday as the world number two kept his foot on the gas in the race to finish the year atop the world rankings.

Djokovic had already qualified for the semi-finals as group winner, but the Serb was keen to keep the momentum going in his bid to overhaul world number one Murray and he took just 69 minutes to demolish Goffin at London's O2 Arena.
