Palermo have signed once-capped Slovenian international midfielders Armin Bacinovic and Josip Ilicic from Maribor, the club the Rosanero eliminated to reach the UEFA Europa League group stage.
Bacinovic, 20, and the 22-year-old Ilicic have both agreed five-year contracts with the Sicilian outfit, who will meet CSKA Moscow, Sparta Prague and Lausanne in Europa League Group F.
The players passed medical tests on Friday, the day after Palermo got the better of Maribor in the play-off round despite a 3-2 defeat in Slovenia, with Ilicic scoring the second of his side's goals.
Bacinovic has spent his entire career with Maribor, while Ilicic only joined the Slovene First League pacesetters this summer following spells with Bonfika and Ljubljana.
Palermo begin their Serie A campaign at home to Cagliari on Sunday.
