Sanseverino is a youth product of Palermo, and was promoted to the first team in the summer of 2012 after being called up by head coach Giuseppe Sannino to join the senior team pre-season camp. He stayed in the first team also under new head coach Gian Piero Gasperini, and made his professional Serie A debut on 6 January 2013, being featured as a starter in an away match against Parma. He was featured again on 12 May 2013, playing the final 10 minutes of a game against Fiorentina as a replacement to Alejandro Faurlín.
After the team's relegation to Serie B, Sanseverino was permanently included in the first team squad for the 2013–2014 season. He made his league debut on 8 September 2013, playing the entirety of the game in a 3–0 win against Padova under new head coach Gennaro Gattuso. On 31 January 2014 Sanseverino left Palermo to go to Perugia on loan until June 2014.
