Soccer is only required to be used once per article 
As per the 'consensus' on terminology, all single topic articles related to the sport of football are only required to have the word 'soccer' in the title (if necessary) and in the first paragraph (barring references to the archaic term being used for old organisations eg Soccer Australia). All further examples of the name of the sport after this first usage are to be 'football'. I have subsequently started on replacing obsolete terminology (after the single required usage in the first paragraph) where I found it in various articles.
