World number one Novak Djokovic saw off Canadian Denis Shapovalov 6-3 6-4 to win a record-extending fifth Paris Masters title on Sunday in a warning to his rivals ahead of the ATP Finals.

The Serbian faced only one break point in another impressive display to claim a 34th career Masters title against world number 28 Shapovalov, who was playing his first final at that level.

Shapovalov, who will reach a career-high 15th in the ATP rankings on Monday, ended the tournament with a sense of pride, knowing that there was little he could do against an almost unplayable Djokovic.

“Credit to Novak,” he said. “Of course it’s a tough ending but he was the better player,” added the Canadian, who has now lost all four of his matches against 16-times grand slam winner Djokovic.

Djokovic, who started the week with a cold, is now one Masters title shy of Rafael Nadal’s all-time record and on Sunday, the 32-year-old was untouchable at the Bercy arena.

The Serb was never threatened in the opening set, dropping only four points on serve as Shapovalov looked tight having not played on Saturday following Nadal’s withdrawal.

The 20-year-old faced a break point in the first game of the second set, saving it with a powerful first serve but a forehand error on Djokovic’s second opportunity gave his opponent a decisive 4-3 lead.

Djokovic then held serve throughout to snatch a morale-boosting victory ahead of the Nov. 10-17 ATP Finals in London, where he will be looking to secure the year-end world number one spot.
