Andy Murray revealed his hip operation has been “life-changing” as he prepares to make his return to competitive tennis.

Former world No.1 Murray has entered the doubles with Feliciano Lopez at next week’s Fever-Tree Championships at Queen’s Club in what will be his first taste of action since undergoing surgery in January.

“I don’t know how I’m going to feel when I get back on the court, but I feel lucky, I feel relaxed, I didn’t expect to be in this position,” said Murray on Sunday.

“I didn’t know how I was going to feel if I went and had the operation but it’s been brilliant, completely life-changing for me from where I was.

“I’m looking forward to getting back out there but I don’t know what to expect. I’m not putting any expectations on myself because just being out on a tennis court again, and being comfortable and pain free, is enough.

“I’ll enjoy competing. I enjoyed practising, hitting tennis balls, doing all the things I couldn’t do even a few months ago, so we’ll see what happens.”
