Not keen on it personally but most folk seem to join in so Mattman has a point. Don't like the Ultras thing though. Started in Italy with, I think, Lazio. Had both violent and right wing connotations. I saw the power of their group on a visit to the stadium. One end holds about 15 to 17,000 people people. The end was empty until I think, 17 minutes had gone. This was apparently a sign to the directors that the Ultras wanted the club to exend the contract of a favourite player coming to the end of their contract. Amazing, but worrying to watch.
