Following winning his sixth Masters 1000 title of the year in Paris on Sunday, Novak Djokovic believes he has reached his peak.
The Serb saw off Andy Murray in straight sets to win a record fourth Paris Masters 1000 event. The win takes the world number one to six Masters 1000 titles for 2015, a feat no player has achieved until now.
The sixth Masters title can be added to his three grand slams wins, making 2015 a year to remember for Djokovic.
"I think in terms of physical and mental ability, I have reached my peak," said the 28-year-old on court after the match.
"I think I was very solid from the very first point, really protecting the baseline, trying to be the one that dictates the play.
"There was couple of games in the second set where Andy started turning things around, so things could have gone different way as they did maybe yesterday against [Stan] Wawrinka at same stage.
"But I managed to stay tough. It was, all in all, the best performance of the week, and it came at the right time."
Despite the hugely successful year, the ten-time grand slam winner is not taking his foot off the gas just yet, as the ATP World Tour Finals awaits, with Belgrade-native hunting his fourth straight win at the event.
"There is no reason for me to decrease the pace of the training and preparations," he said.
"Hopefully I can finish off the season with another great win."
Meanwhile, Murray heaped praise on his opponent and admitted that it back to the drawing board for him.
"It was a pleasure to play here this week in the beautiful new stadium," said the Scot.
"Congratulations to Novak. It's been a great year for him. It's been a great week for me…first time past the quarter-finals. That's progress and I hope to be back next year."
