Andy Murray is targeting further Grand Slam success after securing his position as world number one at the season-ending ATP World Tour Finals.
The 29-year-old comfortably defeated Novak Djokovic 6-3 6-4 in London to consolidate his position above the Serb at the pinnacle of the sport.
The victory was just the Briton’s third against Djokovic since Wimbledon in 2013, and it is clear that he took immense satisfaction from the win.
"It was obviously a big, big match against someone who I've played so many big matches against in my career, that would be my main rival really throughout my career," Murray was quoted as saying by BBC Sport after Sunday's victory.
"We've played in all of the Slam finals, Olympics, obviously here now, and a match to finish the year number one. It was a very important win for me."
Murray: The majors motivate me
However, as with any top athlete, he is already looking to the future and creating new targets to strive for.
“Now that I’ve got there, I obviously would be motivated to try and stay in that position,” Murray continued. “But the majors get me working hard – they really, really motivate me."
Whirlwind year for Murray
It has been a whirlwind season for Glasgow-born star, who has sustained incredible performance levels since his second Wimbledon triumph in July.
A gold medal at the Olympics in Rio was to follow, before a 24-match winning streak which culminated in yesterday’s relatively comfortable triumph at the O2 Arena.
A well-deserved break is now on the agenda for Murray, before training resumes for a new season and another attempt to claim the as yet elusive Australian Open title.
Once again, it is likely that Djokovic will constitute his main rival. The Scot has lost four finals to Djokovic in Melbourne and will be looking to go a step further in 2017.
"When I go away in December to train, I'm training with the Australian Open in mind," he added. "Because of the best-of-five-set matches, they're the ones you have to really put in the extra work for and the extra training for. That's what motivates me."
Djokovic congratulates Andy - and Kim
Having cruised past Kei Nishikori in Saturday’s semi-final, Djokovic was below par on the day, committing an unusually high number of unforced errors.
However, despite his obvious disappointment, he was as gracious as ever in defeat.
"There was no serious chance for me to win today's match," admitted the Serb. "From the very beginning we could see that. He was just a better player all in all. It just wasn't my day.
"On the other hand, credit to Andy for being mentally tough and playing the right shots, making me play extra shots in every rally. He definitely deserved to win."
Djokovic ventured further to praise Andy’s wife Kim, who gave birth to their daughter Sophia in February.
"We should all let Andy enjoy this a little bit," he said. "Don't ask him questions about next season. He deserves to be in the moment and to really take everything in that he achieved.
"His team as well, and his wife. She has to get some credit, guys. She gave birth this year. He has travelled all over the place.
"I know how it is with my wife Jelena, what she had to go through as a mother back home with a little baby.
"So, Kim, well done. She's maybe made even a bigger effort than Andy."
