TAMPERE, Finland — When the referee’s whistle sounded at the end of the first half on Saturday, Juha Kumara’s hamstring ached so badly that he took himself out of the game and limped into the stands.

Not to the bench, mind you. As a former spectator himself, Mr. Kumara was accustomed to watching from the stands. Strangest of all, though, was that there was a fan section at all. This particular soccer match was being held deep in the minor leagues of Finnish soccer, where normally no more than a dozen people bother to watch.

Yet the crowd of 200 on the sidelines rollicked and roared enthusiastically with every good play, wearing blue-green scarves around their necks and holding up an elaborate display of team posters and a giant banner that required a dozen fans to manage.

“We have the best fans in town,” said the coach, Mika Suonsyrja. “If you have two of them, they will start singing.”
