Novak Djokovic came out of a set to defeat Daniil Medvedev 4-6 6-3 6-3 and win the Paris Masters on Sunday.
Djokovic lost to Medvedev in the US Open final in September, with that defeat ending his hopes for a Grand Slam on the calendar.
But the Serbian, whose semi-final victory over Hubert Hurkacz assured him of being world number one at the end of the year for a record seventh time, took his revenge in France.
Mark a fifth title of the year and a sixth triumph in this event for Djokovic, who did not participate in the tournament last year – Medvedev won it in his place.
The 34-year-old got away with anything but his own way, with Medvedev suffering a break up, and although Djokovic retaliated to equalize at 2-2, the world number two kept a second break point at bay before taking the lead to 4-3.
However, after serving the first set on first request, the US Open champion slipped into the fourth game of the second when Djokovic pulled off some superb returns, and didn’t look back.
With the momentum and the crowd on his side, Djokovic broke Medvedev twice in quick succession in the decider and, although he was denied to claim victory over his serve, he simply delayed the inevitable.
Medvedev’s powerful serve wasn’t enough, with Djokovic keeping his cool to seal a record-breaking 37th Masters 1000 title with a sublime forehand into the corner of the pitch after a grueling exchange.
