Andy Murray has expressed his disappointment about his surprising Wimbledon quarter-final defeat by Grigor Dimitrov, admitting he had no excuse as the Bulgarian was much better than him.

Dimitrov beat the current Wimbledon champion in a 6-1 7-6 (7-4) 6-2 straight sets defeat – even though Murray had not dropped a single set during the earlier rounds of the tournament.

Speaking to the BBC about the defeat, Murray said: "As much as I'm disappointed with my level, Grigor did play a very good match. He didn't give me many opportunities.

"I was nervous, I felt the butterflies and was excited about the match, but that's perfectly normal. I didn't feel overcome by the moment, but I certainly wasn't very good when I got out on court.

"I made a bad start and I think that gave him confidence, and then there were just too many errors from me. All the percentages were going in his favour."

Murray has not reached a final since his Wimbledon 2013 victory but is confident about the future.

"Now it's about regrouping and working out what I need to do to get back to my very best. I'll sit down with my coach Amelier Mauresmo and decide how we're going to take things forward. That's as much up to her as it is me," he said.

"I've really enjoyed the last couple of weeks, so we'll see where we go from here. The game always improves and gets better, and I know I have things to work on. I plan to be back on the practice court and in the gym soon.

"I need to get a bit more out of myself and gain as big an advantage as possible when I step out on the court. Hopefully I will be back at Wimbledon next year after 12 months of hard work and be in a position to challenge for the title again.

"Centre Court is a special place and I truly believe I can have some more great moments out there."
