Andy Murray has spoken of re-setting his goals after six months out injured but still believes he can compete for Grand Slams.
The British number one is preparing to make his comeback in the sport amid reports that he may no longer be able to sustain the quality he produced in winning two Wimbledon titles, a US Open and reaching the top of the ATP rankings.
"When I was fit and healthy last year  you think about winning all the major events, getting to No 1 and winning every competition that you are in and that is what really drives you,” said Murray.
“When you miss four or five months and there has been a bit of uncertainty about my hip or stuff, [that changes].
“I missed the US Open and almost missed Wimbledon as well.
“The goals change and I remember now how much I just loved playing tennis - it isn't about winning every match that I play in the future or winning more slams."
Murray, 30, now ranked 16 in the world, is scheduled to enter the Australian Open on January 15 - assuming he suffers no setbacks in his injury comeback.
He added to Sky Sports: "I want to get back to playing tennis, I want to be fit and healthy and that is what is driving me just now.
"I am hoping next year I can get back to that and if I do [get back to being fit and healthy] then I have an opportunity to compete for the biggest tournaments in the world and I still believe that."
