Napoli head coach Maurizio Sarri has joked that he will greet Gonzalo Higuain in the same way "a father would with a son who made him angry" when they meet again this weekend.
The Argentina forward joined Juventus in July, having spent three seasons in Naples and scored 71 Serie A goals.
Higuain enjoyed a great relationship with the Napoli fans, but that turned sour when he sought a move to Juve, with whom he will host his former club in Turin.
However, Sarri was in a light-hearted mood when asked how he would react to Higuain after Napoli beat Empoli 2-0 on Wednesday.
"Higuain did well with me and was always hard working in training," he told Sky Italia.
"How will I greet him on Saturday? In the same way that a father would with a son who made him angry."
Higuain's former Napoli team-mate Dries Mertens was slightly less forgiving, though, emphasising the importance of a win against the champions.
"There is no such thing as friends on the field," he told Mediaset Premium. "It's an extremely important game. I'll give him a slap round the face."
