While we're putting the world to rights on the terminology of soccer, can we correct the idea that Cardiff won the FA Cup in 1927.
Cardiff won the English Cup in that year.
As Cardiff is not in England the Football Association decided that the competition needed to be re-named (for future tournaments).

So names in soccer can be changed. The 'World Cup' was also re-named The Jules Rimet Trophy (but it never really caught on)
