Novak Djokovic fought off a stern challenge from Pierre-Hugues Hubert to make a successful start to his French Open title defence on Tuesday.

The world number one held off the challenge of the home favourite to win 6-4, 7-6 (7-3), 6-4, setting him on his way to a potential 25th Grand Slam title.

Djokovic enjoyed a fairly comfortable first set but had to work hard to win the second as Hubert took a more aggressive approach. He steadied in time for a crucial tie-break though, holding his nerve to secure it.

The Serbian regained control in the final set, sealing the win after a double fault from Hubert to set up a second-round tie against Roberto Carballes Baena.
