Liverpool manager Jurgen Klopp is wary of a Napoli side he describes as "stubborn in a very positive way" as the Reds begin the defence of their Champions League crown at the Stadio San Paolo.
The clubs have been drawn in the same group for the second season in a row, with Napoli prevailing in the corresponding fixture last term as Lorenzo Insigne's late strike settled matters.
Liverpool went on to pip Napoli to a spot in the knockout stages – by virtue of scoring more goals after they finished level on points and a number of other determining factors – before going on to lift the coveted trophy.
"We want to create more stories to remember in the future and not only this one, so we cannot stick to that.
"If you go nuts and start taking drugs and drinking and driving different cars or whatever and leave your missus at home because you are now the Champions League winner then I can't help you. But we are not like this."
Klopp laughed off suggestions scooping the Champions League title makes Liverpool the best team in Europe, adding: "We cannot be the best team in Europe because Man City is the best team in the world, that's the same planet!"
Napoli summer signing Fernando Llorente is out for revenge against Liverpool, having been part of the Tottenham side that were beaten in last season's Madrid final.
He told a press conference: "I'm still bitter about losing in the final against them last year and I really hope I can settle the score this time around as a Napoli player.
"Napoli can make an impact in the Champions League this season. At Tottenham last season, we certainly weren't touted as one of the favourites, yet we reached the final."
