A spate of injuries sidelined Sparagna for large parts of the first half of the following season and, by the turn of the year, he had made only three league appearances. He made his long-awaited return, and only other appearance for the season, on 19 April 2019 but scored an own goal to consign Boavista to a 1–0 defeat to Tondela. That proved to be his final appearance for the club as in January 2020, having not been registered by Boavista for the 2019–20 Primeira Liga campaign, he was allowed to leave the club on a free transfer.
