Bersano began his career with Deportivo y Cultural Arroyito, who preceded his move to Talleres.[3] He was promoted into the Primera División club's first-team squad midway through the 2018–19 season, though he had signed his first pro contract back in November 2016.[4][5] Having impressed in mid-season friendlies in January 2019, the defender signed a new two-year contract on 24 January.[6] He made his professional debut under manager Juan Pablo Vojvoda on 27 January during an away draw to Independiente; he featured for the full duration.[2][7]
In February 2021, Bersano was sent out on loan to Primera Nacional club Villa Dálmine until the end of the year.[8] After returning in January 2022, he was sent out on loan again, this time to Deportivo Morón, until the end of 2022.[9] However, the spell at Morón was terminated before time, and joined Gimnasia Mendoza on 23 June 2022, on a one-year loan.[10]
