Former world No.1 Andy Murray is still hoping to make a return to singles competition this year, but the Brit said the U.S. Open looked too soon.

Speaking about how he would have felt six months ago if somebody had told him that today he would have been in this position, Murray said: "It's the pain-free aspect that was the most pleasing thing for me. I mean, I kind of got used to dealing with the pain and I was kind of ready for that to be over with. But it's difficult."

He continued: "When you have been in pain for a long time it's hard to remember what it was like beforehand and now I am back to being pain-free again and it's just nice, I can go and enjoy things, you know, off the tennis court as well, which I wasn't doing for a while. But then obviously when I am in the gym and on the court as well it's a lot easier to have fun and enjoy stuff when you are not in discomfort." 

The three-time Grand Slam champion added that he didn't want to put a time frame on when his return to singles would be. Murray underwent hip surgery in January, soon after a tearful news conference at the Australian Open when he said the tournament could be his last after almost two years of injury problems.  
 

The 32-year-old was competing in the doubles with Feliciano Lopez at the Queen's Club grass-court event next week. He then planned to play doubles at Wimbledon.
