Roy Hodgson's England side are pampered professionals paid millions of pounds to concentrate on football.
But analysis of the England team that won Olympic gold for Great Britain in 1912 showed it included a sculptor, an architect and a dental surgeon.
The Great Britain Olympic team which won gold: (back row, l-r) reserve George Barlow, linesman F Styles, Walter Corbett, Horace Bailey, RM Hawkes, FA Council member A Davis, linesman JR Schumacher, referee J Lewis (middle row, l-r) Herbert Smith, Harry Stapley, Vivian Woodward, CH Purnell, Harold Hardman, Rev Kenneth Hunt (front row, l-r) Arthur Berry, Fred Chapman
With no World Cup or European Championship a century ago, the Games were the pinnacle of international football achievement.
Analysis of Census records from 1901 and 1911, and a study of their lives and careers, has revealed how the winning team spent their time off the pitch.
They were captained by Vivian Woodward, a successful architect and surveyor, while star striker Gordon Hoare was a sculptor by trade.
Ronald Brebner clearly had a safe pair of hands as he was a goalkeeper and a dental surgeon.
