Surprising secret about sports hero David Beckham is finally revealed

David Beckham is arguably one of the most photographed men in the world.

So it has come as a surprise to discover that despite such intense coverage there is still more to learn about this superstar.

The dad-of-three was seen using an inhaler at half-time during LA Galaxy's cup final on Sunday, which his team eventually lost 5-4 on penalties.

Incredibly, although he has played for big-name teams including Manchester United, Real Madrid and England, the 34-year-old has never before been seen using a 'puffer' – despite living with asthma since he was a child.

The dad-of-three's agent has confirmed that he does have the condition, saying: "David has suffered with this since he was a young boy."

"He has never sought to make it public but if it does inspire any sufferer to think they can achieve great things like many other sportsmen have done then so much the better."

Sunday's game marked the end of a tough season for David, who has a short time to rest before getting back to work.

He will spend Thanksgiving with wife Victoria and their three sons in LA before travelling to South Africa to help England's bid for the 2018 World Cup bid.

And then after Christmas he will head to Italy to rejoin AC Milan in time for the start of the football league in January.
