Palermo striker Fabrizio Miccoli fears their home game with Juventus will feel like an away clash.
"I hope that of the 35,000 people in the crowd, at least 30,000 will be cheering us on and not 15,000 to 20,000 for Juventus," he told the Giornale di Sicilia newspaper.
There is the concern that local tickets will be snapped up by Juventus supporters to pack out the Stadio Renzo Barbera on Sunday night.
