Perrotta wants Roma move
Chievo are reluctant to offload Perrotta during the summer but are fielding heavy interest in the player.
European champions Porto - now coached by former Chievo chief Luigi Delneri - have repeatedly tried to sign Perrotta.
Serie A giants Roma have also had a long-standing interest in the midfielder and are gradually defining their transfer targets.
They are now likely to increase their efforts to land Perrotta after Chievo sporting director Giovanni Sartori confirmed the player wants a transfer to Stadio Olimpico.
"Perrotta wants to go to Roma," Sartori told a Roman radio station.
"I can't unbalance myself about the possibilities of him arriving at Roma but there are many clubs who are looking to sign him.
"There is, firstly, Porto's interest but he wants to go to Roma."
