David Beckham searches for the next big thing in sport

David Beckham might have retired from football last year, but that hasn't stopped him from playing a prominent role in the build-up to the World Cup.

Having already made it to Brazil - the venue for this year's tournament - in his BBC documentary Into The Unknown, the 39-year-old star has now fronted a new TV advert, which will launch in the first ad break for the FIFA tournament.

David Beckham's latest advert

It sees David vetting a series of new, top secret innovations in sports - including drone cameras over a cricket pitch, a suit that lets viewers experience the same physical impacts as a rugby player, and the chance to play Sofa Ref in X Factor-style voting for refereeing decisions.

Ultimately he rejects each idea before unveiling the best new concept – Sky Sports 5, a channel launching in August, dedicated to European and International football.

Just recently, David set his sights on a new goalfronting a new campaign with Prince William in support of endangered species.
