Today marks the 91st anniversary of the opening of San Siro, with Inter beating Milan 6-3 in the first match.
The idea to build a privately-owned stadium specifically for football was the brainchild of then-Rossoneri President Piero Pirelli.
Most stadiums in Italy which were publicly financed had running tracks around the pitch to make them multi-purpose, a feature seen at the Stadio Olimpico, the Stadio San Paolo and previously at the Stadio Delle Alpi, before it was turned into Juventus Stadium.
