Annibale Frossi (; 6 July 1911 – 26 February 1999) was an Italian football manager and player, who played as a forward.
Frossi is perhaps best known for wearing correctional glasses during his playing years after suffering from myopia from when he was a child. As a footballer, he was a member of the Italy national team, which won the gold medal in the football tournament at the 1936 Summer Olympics, finishing the tournament as top-scorer. As a manager, he is also known for his developments of the theory of catenaccio, which emphasises a defensive style of football. Frossi began his career as a professional footballer with Udinese, and, after a long stay in Serie B (with Padova, Bari, and L’Aquila), he was acquired by Ambrosiana Inter, where he made his debut on 21 June 1936, in Mitropa Cup. After that, Frossi was called up for the 1936 Summer Olympics by Vittorio Pozzo, the coach of the Italy national side, leading the team to the victory of the tournament with his prolific performances. In the following years, Frossi played with Inter from 1936 until 1942, winning the “Scudetto” or league championship, twice in 1938 and 1940, as well as the Coppa Italia in 1939. He scored 49 goals in 147 matches with Inter, 40 of which came in the league, in 125 appearances. He was called up by the national team manager Vittorio Pozzo for the 1936 Summer Olympics in Berlin, where he made his international debut along with the other members of the Olympic team, scoring a goal in a 1–0 victory over the United States on 3 August; He also made one appearance for the Italy B-side in 1937, in a 3–2 win over Austria on 21 March. He made his final and only other appearance with Italy in a 2–0 win against Hungary on 25 April 1936, scoring a goal.
Style of play
Frossi was an extremely fast right winger both with and without the ball, who possessed a keen eye for goal, which also made him capable of playing as a centre-forward. According to Gianni Brera, he was known in particular for his pace, energy, and coordination; he was not the most technically gifted footballer, however, and was also not particularly good in the air or acrobatically, as he needed to play with glasses due to his myopia. Vittorio Pozzo Described him as an excellent opportunist in the penalty area. Frossi was also known for his accurate shot and striking ability from outside the area, as well as his tactical intelligence, which made him an excellent executor of his team's set-plays.
For his short (12 matches) tenure as coach at Internazionale, Frossi did the job jointly with manager Luigi Ferrero, a strong advocate of attacking football. Despite an 11 match unbeaten record, Inter dispensed with his services because of dissatisfaction with his tactical style and it seemed that Ferrero had won the battle of ideas, together with influential players such as Enzo Bearzot. Despite this, it was the defensive footballing theories of Frossi, Nereo Rocco and later Helenio Herrera which became dominant in Italian football for the 25 years or so after his time at Inter. Frossi died on 27 February 1999, at the age of 87, at the San Raffaele Hospital in Milan, after contracting pneumonia. Following his death, in his home town of Udine, a city street near the local Friuli Stadium was named after him in his honour.
