It will be the first time he's returned to his former club since leaving for Chelsea.
“It is a special game for me, but we mustn't spend too much energy on personal issues and focus on the collective," said the coach in his press conference.
“We have a very important match to play. If the fans did jeer me, I would consider that a show of affection. They were unfair to do that to Gonzalo Higuain, though.
“If Higuain plays tomorrow or not is purely a tactical consideration and has nothing to do with the atmosphere."
Sarri was asked if coming to Juve meant he could never return to Napoli in future and made a surprising revelation.
“I am not thinking about that now. After this experience, I could even retire. We'll see how much energy I have left by the end of it.
“Pressure is not really an issue, it's about what someone expects from themselves. If you focus on the circus, then you're done for. I don't know how I'll feel when my contract expires in two years. I might even continue and it'd be a bad idea."
