Andy Murray says finishing the year-end world number one has motivated him to push on and build on his success in 2017.

The Scot beat five-time champion Novak Djokovic to win his first ATP World Tour Finals title on Sunday, a victory that will see him end 2016 in pole position.

It extended Murray's winning run to 24 matches, earned him a fifth straight title and a cheque for nearly £2m.

Earlier this year the Scot also won a second Wimbledon crown and retained his Olympic title.

"Obviously it was a big match against someone I've played many big matches against - my main rival throughout my career," he said.

"We've played in all the slam finals, the Olympics, obviously here now in a match to finish the year world number one. It was a big match and a very important win for me.

"This is a major event and one that I've not done well in in the past so it's been a great week."

He added: "I would like to try to stay there obviously, it has taken a huge effort in the last five/six months to get there. It's going to be extremely difficult because I've had a great year and I only managed to do it by one match.

"To repeat that again next year is going to be extremely difficult but now that I've got there I'm obviously going to be motivated to try and stay in that position.

"I want to achieve as much as I can these next few years, I won't be around forever or be able to play at this level and this many matches in my mid-30s so these next few years, I want to make them the best of my career."

Novak Djokovic, the man Murray defeated to retain his title, said: "Today we were both part of history, it was an honour to be on the court. Andy is clearly number one of the world, he's the best player.

"He played the best tennis in the decisive moments. I wasn't able to come back. I started playing a bit better but it was too late. I congratulate Andy and his team for a great year."

Former British number one Tim Henman believes Andy Murray's achievements should inspire the next generation to play tennis.

"It's imperative of the LTA and the game of tennis in this country that they capitalise on it," the 42-year-old said on BBC Two. They have an unbelievable role model.

"It's been such a journey. He's overcome so many hurdles but this has to inspire the next generation to play the game and produce better players going forward.

"It defies logic, it really does. Every time there's a challenge put in front of this man, he finds a way to get over it."

Greg Rusedski, another former British number one, told Sky Sports 3: "I want to know from Murray, how he recovered from (Saturday) because that was astonishing."

"It was all about his brilliance. He served well, he was aggressive. This is the best match Murray has played throughout this championship and that's why he is the number one player.

"Don't take anything away from him - he was the better man today - it wasn't Novak playing poorly.

"What a performance, what a result... incredible."
