Andy Murray has opened up about being labeled 'moody' earlier in his career and revealed that another injury could force him into retirement.

Former world No. 1 Murray has been a well-known face in the tennis world from a young age, winning his first ATP title at just 18 years old back in 2006. Following this, the Scot has had a hugely successful career, winning three Grand Slam titles and reaching the top of the ATP singles rankings in 2016. 

However, the 36-year-old has struggled with injuries in recent years and his form has dropped somewhat as a result. Nevertheless, he is still playing well, particularly this season, during which he won his first title since 2019 at the Aix-en-Provence challenger event and is currently competing at the DC Open, where he is into the second round.

In a recent interview with The Times, Murray admitted that his being called moody wasn't entirely unjustified early on in his career, as he struggled to adapt to the limelight.

"I found the whole experience of my life changing overnight at 18 years old very difficult," he said.

"Everyone makes lots of mistakes when they’re a teenager. For most of the population, that doesn’t happen in front of millions of people. All the attention was not something I was very well prepared for."

However, he added that the label itself never really bothered him:

"I wasn’t too bothered about being portrayed as “moody”; some of that would have been fair and justified."

Despite struggling to re-gain his form of seven years ago, Murray has still been enjoying competing in the sport he loves and has no plans of stopping yet. Nevertheless, he admitted that another injury could possibly signal the end of his career.

"I don’t want to have played my last match at Wimbledon, I’m still planning on continuing. But you never know with my age. Another injury could be the end. You can’t predict it."

Although retiring is often a totally new prospect for players, Murray insisted his experience with surgery that risked putting him out of the sport a few years ago means he's not worried about how he'll cope with the change when it does come.

"I’m not worried about what I’ll do when I finish playing. Before I had surgery, I had to accept that I might not play again. So I went through that process mentally and although it was hard, I accepted it.

"The good thing about the six months of rehab after the operation was I got to feel what being a retired tennis player would be like. I spent time at home with my family, played lots of golf. I really, really enjoyed it — I’ve got lots of things to look forward to."
