Novak Djokovic reached his 13th grand slam tennis final and second at the French Open on Friday, bringing to an end the colourful Paris campaign of giant-killer Ernests Gulbis.

The world number two triumphed 6-3 6-3 3-6 6-3 and will face either top seed and eight-time champion Rafael Nadal, who beat him in the 2012 final, or Britain’s Andy Murray for the title.

Victory on Sunday would make Djokovic only the eighth man in history to complete the career Grand Slam.
