"He is an exceptional player, who has forged ahead. We like him very much," Sabatini told reporters. "He is a player that we would like and we will discuss him through correct behaviour, we will not wait for a solution to acquire him on a free transfer.
"If we have the privilege and the desire to negotiate for Rabiot, we will do so in agreement with Paris Saint-Germain.
"But I believe it will be difficult, as his contract situation is unknown. We will try to work on this as something between clubs of great prestige."
Rabiot's existing deal is thought to expire next summer.
