Palermo president Maurizio Zamparini is convinced they will qualify for the Champions League.
The Rosanero face a virtual fourth place playoff this weekend against Sampdoria.
"I have seen Palermo play very concentrated and decisive," Zamparini said. "We met a team who are playing well. I remember when Siena were three goals down against Juventus and managed to comeback.
"Palermo and Samp deserve their positions in the table. It will be a wonderful game.
"I am convinced that we will do it because we are stronger at home, but we'll need to be careful.
"The Champions League 90 per cent depends on Sunday."
