Andy Murray has revealed he is working hard on his game in Miami in a bid to be ready to start 2017 on the front foot.

The Scot claimed the number one ranking after his victory at Paris Masters in November, become the first British player to achieve the feat since rankings were introduced in 1973.

Having displaced Novak Djokovic from top spot, the Wimbledon champion had to defeat the Serb in the ATP World Tour Finals decider at London’s O2 Arena to hold his ranking for the year-end.

He recorded a straight sets success to win the season-ending tournament for the first time and retain his top ranking.

On Sunday, there was more personal accolade for Murray as he named BBC Sports Personality of the Year for a record-breaking third time.

The 29-year-old is the first person to win the award three times and he accepted from his training camp in Miami.

Murray revealed he is putting in the hard work now in order to stave off the inevitable fightback from Djokovic in the New Year.

“I’m sure Novak will be wanting to get back to the top spot but it’s taken me so long to get here that I want to stay there as long as I can, and that’s why I’m over here now,” he said.

“I’m working on my game and trying to get myself in shape so I can start 2017 as best as possible.” Murray will hope to start 2017 with a first ever victory in the Australian Open.

He’s been runner-up in Melbourne on five occasions. Murray is 2.50 to win the season’s opening Grand Slam, with Djokovic 2.40 to retain his crown.
