Napoli coach Carlo Ancelotti has hinted PSG approached Allan without their permission this month.
Ancelotti is adamant Allan won't leave before Thursday's deadline.
He said, “I won't get into negotiations that are ongoing. As far as I am concerned, the matter is over, Allan will remain our player and we never intended to sell if not for something extraordinary.
“The player has been contacted, even though that shouldn't happen, and we listened to his requests, after which nothing happened. He will stay with us and play on Tuesday."
