The British legend brought an end to his career at the Olympics this summer and confessed that he has not been missing the sport like he suspected he would.

Murray told BBC Radio 4's 'Today' programme: "Since I've stopped, I feel really free and have got lots of time to do whatever it is I want.

"I can dedicate time to my children and have free time to play golf or go to the gym on my own terms.

"It is really nice and I didn't expect that. I was expecting to find retirement hard and be missing tennis a lot and wanting to get back on the tennis court on tour.

"So far it has been the complete opposite to what I was thinking."

Murray explained that he no longer feels a sense of "guilt" around his wife Kim and their children as he doesn't have to spend weeks away from them while on the tennis tour.

The former world number one said: "The thing that I always found difficult in recent years was that there was always a guilt associated with what I was doing.

"If I was going away for a trip of like three to four weeks I would feel guilty leaving my children at home or being away from my wife for a long time with them, so missing the kids I found hard.

"But if I was at home with the kids then I was running around and spending a lot of my time on my feet after training.

"I was then thinking, 'Is this going to affect my training or performance the next day, should I have my feet up?' I found that stuff difficult over the last few years."
