Enrique Omar Sívori (Spanish: [enˈrike oˈmaɾ ˈsiβoɾi], Italian: [ˈɔːmar ˈsiːvori]; 2 October 1935 – 17 February 2005) was an Argentine-Italian football player and manager who played as a forward.

At club level, he is known for his successful time with Italian side Juventus during the late 1950s and early 1960s, where he won three Serie A titles among other trophies; he also played for River Plate in Argentina and Napoli in Italy.

[2] Sívori was born in San Nicolás de los Arroyos, a town which falls within the Buenos Aires Province, in an Italian Argentine family.

His paternal grandfather, Giulio Sivori, was an immigrant from Cavi di Lavagna, a hamlet in the province of Genoa, while his mother Carolina was of Abruzzese descent.

[3][4][5] As a youngster Sívori became heavily interested in the game of football and by the time he reached his teens he was signed up to a side from the city of Buenos Aires, River Plate.

[3][6] The teenage Sívori was given a chance to break through into a squad which included players like the famed forward Ángel Labruna and Félix Loustau who established themselves in the era of La Máquina, one of the foremost formations in football history.

[3][11] However, they were able to complete their El Monumental stadium (previously nicknamed "the horseshoe") by adding a fourth stand bearing his name, with the money from the deal.

[3][14][15] The same year as his personal achievement however, the Magical Trio as they were known, had broken up with Boniperti's retirement and the following season John Charles moved back to Leeds United.

Sívori stayed on with the Old Lady, notably scoring the only goal in a 1–0 victory against Real Madrid, making Juventus the first Italian side ever to win at the Santiago Bernabéu Stadium.

Sívori wore the number 10 shirt[16] and was appointed the team's captain in 1963, but did not win any more championships or trophies with Juventus, and left after the 1964–65 season, because of a disagreement with new coach Heriberto Herrera.

[18] The Argentine side of the time had a formidable attack with Sívori, Oreste Corbatta, Osvaldo Cruz, Humberto Maschio and Antonio Angelillo.

Sívori was a quick, diminutive, highly creative, and technically gifted forward, known for his pace on the ball, who used his acceleration, outstanding dribbling skills, flair, and feints to beat opposing defenders; these included turns, flicks, quick changes of direction, and his innovative trademark move: the nutmeg, also known as tunnel, in Italian, which involved him playing the ball between an opponent's legs.

Despite not being particularly strong, due to his slender physique, Sívori was also known for his tenacity and bravery on the pitch, as well as his professionalism as a footballer, although he also drew criticism at times for his volatile character and unsportsman-like behaviour, which often saw him argue with officials, commit aggressive tackles on his opponents, or attempt "to provoke and to humiliate" other players with his skill on the ball.
