The 40-year-old retired soccer star - who has kids Brooklyn, 16, Romeo, 13, Cruz, 10, and Harper, four, with wife Victoria - admits he hasn't yet got to grips with balancing his work and home life because he loves being around his family so much.

He said: "I get physically ill when I have to leave the kids now."

When he is at home, David can mostly be found watching 'Frozen' with his daughter or binge-viewing old episodes of 'Friends'.

Though he retired in 2013, David admitted he misses his sport every day and sill considers a return to the game.

He told Britain's GQ magazine: "I miss soccer every day. I don't know whether it's the athlete in me, or the passion I have for the game: I always think that I can step back on the field and play...

"You know, maybe I could play another year in the US. If I was still living in LA, I'd probably really seriously think about coming back for a year. But we're living in London, and the kids are happy in the school..."

Though he and his fashion designer wife generate headlines wherever they go, David insists he no longer cares or worries about what is written about him.

He said: "I'm secure as a person, as a husband, as a dad. I've gone past the point of really worrying, caring."
