Paratici has opened the door for Mario Mandzukic to start training with another side ahead of a January transfer move.
The striker is still being linked with Manchester United.
"We are talking to Mandzukic to find the best possible solution," Paratici told Sky Italia.
"We remain open to any scenario, so staying here or going elsewhere. We are discussing it to find the best solution for both parties.
"Mandzukic is not training with us, in agreement with the club. If the agreement changes, I am open to everything."
