David Beckham says receiving a knighthood would be an "unbelievable honour"

The former England football skipper has been a UNICEF ambassador for 20 years, and some have questioned why he is yet to receive a knighthood for his services to football and charity work.

He told Time Magazine: "I've heard people in the media talk about it's something that I really, really want, and of course, it would be an unbelievable honour.

"If it happens at some point, amazing. If it doesn't, there's nothing I can do about it."

During his playing days, David won 115 caps for England, and he captained the Three Lions 59 times.

While he is now a co-owner of Inter Miami CF and Salford City FC, David still misses his playing and training days.

He explained: "There's a lot of players that say, 'Oh, well, I miss the locker room. I miss the banter.'

"I don't miss any of that, because I have that with my family and with my friends. I miss training every day.

"I miss playing every weekend. Every day, I wake up, and I feel like something's missing. Even at 50 years old, in my head, I can still play."

Despite no longer training with a football team, David keeps fit.

His wife, Victoria Beckham, admitted her husband spends around an hour in the gym, but she is there for nearly two hours.

She said: "David does an hour in the gym, and I do an hour and 45 minutes."

But David insisted he "works harder" than his 51-year-old significant other - who he married in 1999 - when it comes to keeping fit.

He joked: "I let Victoria believe that she's working harder.

"But I think I'm the one that's working harder. Don't tell her that."
