Defending champion Novak Djokovic came storming back to reach round four of the French Open tennis.

The Serb was taken to five sets by Argentina's Diego Schwartzman, but eventually won 5-7, 6-3, 3-6, 6-1, 6-1.

He will now face the winner of Lucas Pouille and Albert Ramos-Vinolas.

Djokovic, who has made drastic changes to his coaching team and has brought in tennis great Andre Agassi to assist him, had found himself two sets to one down on his opponent.

But he dominated the final two sets 6-1, 6-1 to advance.

Earlier, nine time French Open champion Rafael Nadal also made it through to the fourth round after beating Nikoloz Basilashvili far more comfortably by a 6-0, 6-1, 6-0 score.
