After 3 straight season finale titles, world No 1 wants to complete major collection with Roland Garros crown

Novak Djokovic has set his sights on finally ending his long wait to be crowned French Open champion next year and complete a career Grand Slam.

Djokovic brought the curtain down on his 2014 campaign in unexpected fashion by playing a hastily-arranged exhibition match against Andy Murray at London's O2 Arena after Roger Federer pulled out of their scheduled ATP Tour Finals showdown just before the match was due to start on Sunday.
