Andy Murray raised doubts over his future after losing in the third round at Wimbledon, leaving the grand slam with one question: "Is it worth it?".

Murray's Wimbledon journey came to an end on Friday following the former world number one's 6-4 6-2 6-2 loss to 10th seed Denis Shapovalov on Centre Court.

Making his first appearance in the main draw since he was the defending champion at Wimbledon in 2017, Murray's career has been devastated by injuries.

Murray underwent hip resurfacing in 2019 but the three-time grand slam champion has continued to be plagued by fitness problems.

After suffering his earliest Wimbledon exit since 2005, Murray was in a downbeat mood as he was left to ponder his next move.

"It was great playing in front of the crowds again," the 34-year-old said. "I got amazing support here. I'm very thankful for that. Something I have missed. It kind of reminds you why you do all of the work and everything.

"But then, on the flip side of that, the positive part is getting through the matches and feeling OK physically and not getting injured.

"That's good but then there is a part of me that feels a bit like I have put in so much work the last three months and ultimately didn't play how I would want and expect, and it’s like, is it worth it?

"Is all of that training and everything that you're doing in the gym, unless you're able to practise and improve your game and get matches and get a run of tournaments, is it worth all of the work that you're doing?

"There is part of me that feels like, yes, it is, because I had great memories and stuff from this event and playing in some brilliant atmospheres. But I finished the match tonight and I'm saying to my team, 'I'm just not happy with how I played'.

"So, unless me and my team can find a way of keeping me on the court for a consistent period of time and allow me to practise the way that I need to to compete with these guys, that's when the discussions about what I do next will come in.

"Because I have genuinely put a lot into this to get to this point, but I'm not being able to practise and prepare how I need to to perform how I would like at these events.

"I’m not expecting and saying I would beat Denis Shapovalov. He's a brilliant player. But I feel like I can do a lot better than what I did this evening."
