"...football .... I concede......originated in England and [rules] were codified here....."
Even FIFA, that paragon of world sporting authority led by their insufferable and unelectable supremo Sepp Blatter acknowledge that world football originated in both Scotland and England. As evidence I offer the fact that the very first international football match was played in Glasgow between Scotland and England, both of whose associations had to endorse the codification of rules in advance.
Hmm.., perhaps on reflection I have shot my own fox by relying on the support of such dubious authority.
