Context: FC Barcelona is a professional association football club based in Barcelona, Catalonia, Spain.  The club was founded in 1899 by a group of Swiss, English and Spanish men led by Joan Gamper.

A super cup is a competition, usually but not exclusively in association football, which often forms the "curtain-raiser" to a season.  It is typically contested on a national level by two competition winners of the previous season: the knock-out cup winner and the league winner.  There are also continental super cups, like the UEFA Super Cup in football, which puts together winners of the top- and second-tier UEFA competitions.  Sometimes these are two-legged ties, with a match played at each side's stadium, but increasingly they are one-off fixtures at a neutral venue, such as a national stadium.  Some Super Cups have even been staged in venues outside their home country, such as the Italian, French, Mexican and Turkish games.
