Bizzotto began his career with A.S. Cittadella. He was first included in a matchday squad on 25 April 2015, remaining an unused substitute in a goalless draw away to Brescia in Serie B. His debut came on 9 May at the Stadio Pier Cesare Tombolato, replacing Daniele Bazzoffia in the 71st minute and nine minutes later netting an equaliser for a 1–1 draw with Frosinone. In a season which ended in relegation to Lega Pro, he made only one more appearance, in a 0–2 home defeat to Perugia 13 days later.
On 2 August 2015, in the first round of the Coppa Italia, Bizzotto netted four goals in a 15–0 home win over Potenza, two goals in either half. A week later in the second round, he opened a 2–0 win at Teramo.
