After still struggling to find space in the Milan first team, Salvatori returned to Fiorentina midway through the 1990–91 season, and remained with the club until 1992, making a total of 45 appearances in Serie A across his three seasons with the team, and scoring one goal. He then transferred to SPAL, and later joined Atalanta, helping the latter club to win promotion to Serie A in 1995, and subsequently reach the Coppa Italia final in 1996.
