I've got an instagram feed which shows supporters and the atmosphere they create at clubs around the world. The European fans are great in Germany, Poland, Italy, Turkey, etc, but my god, the fans in Argentina are something else. Singing in groups outside the ground before and after the match, inside the ground the singing and support is continual involving the whole stadium. I'm not just talking Boca, River, and the other big Argentinian clubs, but the smaller clubs as well. I still don't get the up and down arm waving to every chant. Can't imagine doing that for 90 minutes along with chanting. :-)
