You may ask why when Italian NT played in ECH, you heard the fans singing and DJ playing Seven Nation Army of the White Stripes?
Well I tell you the story
In 2006 Roma Soccer club played against Bruges. The match was held in Bruges and every time the team did something good the DJ started this song. But at the end Roma won, so the fans started chanting the song with the words "po po po po" instead to make rhytem to spoof Bruges. Then everytime Roma played the fans were chanting "po po po po". It has become something usual. Then came the World Cup in Berlin. Now all Italian fans started to sing this song. And after Italian NT actually won the Cup, the song has become the hymn of the Italian NT soccer team and the song of the summer. A lot of remixes have been made. Because of the success the Italian fans started to use the song also in volleyball. In Novara for example it is used when Sanja Popovic enters in court (they sing po-po-po-Popovic, with the DJ playing the song).
The Italian fans at ECH and in the League used:
