Andy Murray said he has come a "pretty long way" from his early days at Wimbledon, when he would eat pizza before facing some of the best players in the world.

Murray admitted he was "very naive" about his diet and not aware of how "big a deal" the tournament was.

The world number one revealed he used to stay in a basement of a nearby house with his mother Judy, brother Jamie and now-wife Kim, and would walk to the All England Lawn Tennis Club before matches.

Murray, who powered through to his tenth Wimbledon quarter-final on Monday, told the BBC: "When I first played at Wimbledon I ate pizza before my matches and was staying in someone's basement, so I've come a pretty long way."

The British tennis star began as a junior at Wimbledon in 2004 before playing as a senior for the first time in 2005.

Murray said of his early days at the tournament: "Of course I knew it was important but in truth I was not really aware of how big a deal Wimbledon was, and how much focus there was on this event.

"I was so young, I just wasn't aware of it. I'd been playing tiny events just a few weeks before that.

"And, yes, I was enjoying pizza for dinner before facing some of the best players in the world."

He added: "I do remember fairly clearly that I didn't eat well. With things like diet, we just didn't know any better and I was very naive."

Murray joked he would be avoiding pizza ahead of Wednesday's clash with American Sam Querrey.
