World number one Novak Djokovic wants the ATP World Tour Finals to move from London in order to "promote" tennis in other areas of the world.

The Serb describes the staging in London as an "immense success" but feels that at the end of the contract next year - after seven years in the capital - it is time for the event to move.

Djokovic beat Stan Wawrinka in straight sets on Wednesday for his 29th consecutive win indoors.
