A tough, physically imposing center forward, Schiavio scored the goal that won the World Cup for Italy on home soil in 1934.
Schiavio was approaching the end of a successful career at Bologna, but playing alongside the great Giuseppe Meazza and prompted from midfield by Luis Monti, he remained one of Italy's most prolific goalscorers.
He scored a hat trick in a 7-1 win over the United States in Italy's opening game, but its passage to the final was far from plain sailing. In the next round, it needed a replay to beat Spain before edging out the dangerous Austrians 1-0 in the semifinal.
The final threatened to embarrass the home side as Czechoslovakia took the lead midway through the second half and then pressed forward in search of a match winner.
But in the dying minutes Raimondo Orsi conjured an Italian equalizer to send the game into extra time. With the home side now pressing forward, Italian coach Vittorio Pozzo repeatedly swapped Schiavio with right winger Enrico Guaita to conserve the pair's energy and confuse the beleaguered Czech defense.
The ploy quickly paid dividends. Just five minutes into extra time Guaita crossed and Schiavio found time and space in the penalty area to beat his marker and shoot home Italy's winner.
