Of course that most of people "doesnt care" because "most of the people" doesnt live in Zagreb, but whole over the Croatia and afaik Medvescak is club from Zagreb.
And about football hype ?
That hype is myth. Sure, hype is there when NT plays at big stage (WC, EC), but otherwise it is just myth. Just because there is football news on front of sports newpapers doesn't mean it is well attended or that people care about it. Our useless league have avarage att about 2000 ( I wrote it too many probably) fans
per round.
Just for example...in 70-s, when Medvescak played derby against Jesenice, front page of "Sportske novosti" had information about it, today Medvescak beats Kazan,Magnitogorsk and you need to find it on latest page. But no suprise there because staff editors of "SN" are people who couldn't find Zagreb on the map 20 years ago...
