In Italy soccer is a real religion and the stadium of Milan, Giuseppe Meazza Stadium also known as San Siro, is called by Milan citizens the "Scala of football", referrring to its importance in soccer game which is similar only to the one of Teatro Alla Scala in the world of opera.
During my trip I attended an Inter FC vs. AC Milan match, in which both teams have met in an appointment always strongly felt in the whole Milan, in its surroundings and throughout the whole Italy.
The effect of Italian supporters is amazing: they really seem to go mad at each attack towards goal of any of the two teams. The choreography was very impressive, and the fans were supporting their favourite team through banners and choirs.
Each fan group has been divided by the opposite one and located in a different area of the stadium. For each goal (the match ended 2-2) Inter and Milan fans cheered every time full of joy for the goal scored or despaired for the goal taken.
After the match I went with my Italian friend Luca (a Milan supporter) out for a drink before returning home. The fans of both teams left San Siro disappointed for the result, but I liked this experience so much that the days after I returned to the stadium just to visit Inter & Milan museum.
