The young midfielder Colpani has had a fantastic start to the current campaign. Over the first four games of the season, he has four goals in Serie A. Colpani scored exactly that many goals over the whole previous season. Over the course of the prior season, he had participated in 27 games. Colpani is now without a doubt a member of Monza head coach Raffaele Palladino's starting lineup of choice.

Along with Matteo Pessina, the captain of the Brianzoli, and former Inter midfielder Roberto Gagliardini, the 24-year-old has established a triumvirate. In the summer of 2020, Colpani first joined Monza on loan from Atalanta. He played for the team for two Serie B seasons, aiding in their 2021–22 season promotion. Colpani was given a long-term contract by the Brianzoli that summer. Since then, he has been a constant on the team. The 24-year-old has been called up to Italy's Under-21 level in the meanwhile.
