Answer
Inter Milan was the Italian club famously managed by Helenio Herrera. Herrera, an Argentine-born coach, led Inter to great success in the 1960s, winning three Serie A titles and two European Cups. His team, known as "La Grande Inter," was renowned for its defensive solidity and counter-attacking style, which revolutionized Italian football at the time. Herrera's tactics and man-management skills played a crucial role in Inter's dominance during that era.
