San Siro is a football stadium in the San Siro district of Milan, Italy. It has a seating capacity of 80,018, making it the largest stadium in Italy and one of the largest stadiums in Europe. It is the home stadium of the city's principal professional football clubs, AC Milan and Inter Milan, who contest the Derby della Madonnina. On 3 March 1980 the stadium was named in honour of Giuseppe Meazza, the two-time World Cup winner (1934, 1938) who played for Inter and briefly for Milan in the 1920s, 1930s and 1940s, and served two stints as Inter's manager.
