During the month of January 2000 he went back to Verona, this time to play with the team of Hellas. On 6 February 2000 he made his debut in Serie A (playing Verona – Fiorentina, ended with a 2–2). The year ended with no goals scored by Cossato. The precarious physical condition allowed him to play only a few times in season 2000–2001 (14 matches, 2 goals). Indeed, on June 24, 2001, during the play-off return to escape relegation in Serie B between Reggina and Hellas Verona, he put off a goal which meant salvation for the team. This made him extremely popular among supporters of Verona.
