David Beckham has revealed that he will donate his entire salary from new club Paris St Germain to charity.

The 37-year-old football icon said he will not earn a penny in wages from his five-month contract - even though PSG, backed by the Qatari royal family, is one of the world's richest football clubs.

Beckham said the money will go to a local Paris children's charity, although he did not disclose the name.

Speaking at a press conference to announce his signing, the former Manchester United and Real Madrid player claimed the prospect of playing without a salary is "very exciting" and "not something that has been done before."

"I am very lucky to have earned what I have earned throughout my career" he added.

Beckham is thought to have a net worth of £125m, and became the highest-paid player in America's Major League when he moved to LA Galaxy on a £4.1 million-a-year deal in 2007.

However it was revealed last May that he had taken a £1.6 million pay cut to stay in America.

Beckham also revealed his family will remain in London, where the children are schooled, and he will commute to his new club on the Eurostar.

England's most-capped outfield player also said he would have to "brush up" on his French. When asked what he can say in the language, Beckham replied simply: "bonjour".
