It's quite an incredible statistic when you think about it - In 21 completed editions only two teams ever have managed to successfully defend the FIFA World Cup title. The Italians did it in 1938, defending the trophy, which they won in 1934.
And then the men wearing the canary yellow jerseys won their first title in 1958 and then defended the trophy - which by 1946 had been renamed the Jules Rimet trophy - in the next edition in 1962.
