If this is anything to go by we certainly got some great global exposure on Saturday. http://www.theguardian.com/football/datablog/ng-interactive/2014/may/19/fa-cup-final-2014-tweets-mapped
There were Russian and other eastern European born fans amongst many nationalities in the city end on Saturday supporting Hull City AFC and there are city fans in Russia. I suspect twitter does not have much of a foothold in Russia, and that the match was not on terrestrial TV; most of the sport on Russian TV has moved to satellite channels.
