I have no idea if soccer is a big deal in Russia or not.
Having watched the game, it was a pretty impressive win to take out Spain, and they played some strong defense to deny Spain many strong scoring opportunities
Akinfeev did a great job in the game to keep them in it and to seal the win in the shoot out while De Gea looked lost in the net when he needed to make stops.

So was the win a big deal?
Or was it sort of like soccer in the US, where its more of a niche for a small subset of people who are actually fans?
