On 22 April 1917, Suppici founded the football club
Plaza Colonia in
Colonia del Sacramento, his hometown. The club's 12 000-capacity home ground has been named
Estadio Profesor Alberto Suppici in his honour. As technical director of
Uruguay, Suppici coached the side to third in the
1929 South American Championship, the precursor to the modern
Copa América. At the
inaugural FIFA World Cup in his home nation of
Uruguay, Suppici dropped goalkeeper
Andrés Mazali, who had won a gold medal in the
1928 Olympic final, from the national team after he was caught breaking curfew and failing to arrive at the team hotel in time in
Montevideo prior to the tournament. Suppici led the side to victory in the final over
Argentina at
Estadio Centenario in Montevideo, masterminding a second-half comeback from 2–1 down to win 4–2 in front of 93,000 people. Suppici's technical staff at the tournament included
Pedro Arispe,
Ernesto Figoli,
Luis Greco and
Pedro Olivieri. He is the youngest ever coach to win the World Cup, aged only 31. ==Honours==
