Perisic had demanded a transfer going into the game.
“It's quite simple. Players can say what they want, but they are employees, they have signed contracts and in order to leave, they need someone willing to pay for them," Spalletti told Sky Sport Italia.
“You can't leave for free and with your salary paid by someone else. If, as Marotta said, he doesn't want to play, then clearly he'll be left out. That's not a problem for me.
“Someone who cannot contribute to the team has to stay out."
