Palermo president Maurizio Zamparini fears Paulo Dybala could wait until his contract expires to leave.
Arsenal, Liverpool and Manchester United have all been credited with an interest in the Argentine striker, who has been likened to compatriot Sergio Aguero.
Palermo have slapped a £31m price tag on the 21-year-old to deter the interest coming from the Premier League.
However, Zamparini worries his agent could convince him to see out his contract until 2016 and leave on a free.
"I find myself in the same situation with Dybala as with [Edinson] Cavani and [Javier] Pastore," the club's president said.
"This year he has exploded, but I already knew that he was very good.
"The lad is now in the hands of some people who don't wish him well. It's difficult to see him staying at Palermo, maybe someone wants to take him away later, on a free transfer."
