The Rosanero insist he won't be allowed to leave for a Serie A rival.
"We are convinced that we will be able to keep him and that he will stay with us," Vice-President Guglielmo Micciche told Radio Kiss Kiss.
"Federico has made it clear that he'd only consider joining PSG, but that hasn't happened because he's not been requested.
"His deal expires in June 2013 and he's already spoken to President Maurizio Zamparini about a renewal.
"The only reason why he would want to leave Palermo is to go to Paris because that is where his wife works."
