[1] Nicknamed El Pibe de Oro (The Golden Kid), Lazzatti is considered one of Boca Juniors's greatest idols, having raised from the youth divisions with a long career in the club.

[1] Lazzatti was born in Bahía Blanca but he grew up in neighbor city Ingeniero White, where he played in local club Puerto Comercial as right inside forward.

With 18 years old, the young promise arrived to the club and played three matches (a friendly one and two in the reserve team) before debuting in the senior squad in 1934 when Boca beat Chacarita Juniors by 3–2 on April 8.

I know I was fortunate because thousand of letters were sent to the club (Boca Juniors) each day, and they just picked my uncle's one and decided to pay attention to it.

In Boca Juniors, Lazzatti formed a memorable midfield line with Carlos Sosa and Natalio Pescia in the squad that won the 1943 and 1944 championships.

Far from football environment, Lazzatti opened a car dealership in Temperley, working there until Boca Juniors called him to take over the team in 1954.

[1][5] Despite that success, he never returned to management, pursuing a career in sport journalism, working in El Gráfico when the magazine was directed by Dante Panzeri.

Nevertheless, Lazzatti continued his career as journalist writing for newspaper La Prensa and in the TV show Deporte con Opinión in Canal 7.
