Napoli coach Luciano Spalletti has warned against complacency ahead of facing Eintracht Frankfurt.

Napoli will defend a 2-0 lead for the second-leg of their Champions League round of 16 tie on Wednesday night.

“There is no secret," smiled Spalletti in his press conference.

“In order to have a great team, you need great players, it's impossible otherwise. Napoli did well to put together this group of great talents, then clearly you also need other qualities like humility, work rate, professionalism, the desire to help out your teammates and not make it about the individual.

“After that, you have to choose a design that you are organised around, for everyone to coalesce around that idea and work within it. If this then all fills the hearts of a passionate crowd like ours, then it all keeps feeding itself."

Spalletti also said, “You can compare it to the first final of the season. It could decide a great deal for the team and put us in the history of this club. I don't think that can put pressure on the side, because I've seen them deal with many positive and negative situations already this term, never getting sucked into the vortex of either reaction.

“Seeing as it is practically a final, I want to see the attitude of a team that is starved and wants a result. I've seen them in training all term and they never let their heads drop.

“Now the test is to forget what has happened in the past and focus on getting the job done now. Don't forget Eintracht got through a group that had Tottenham, Marseille and Sporting. Last year they won away to a Barcelona side that eliminated us, so we have total respect for the work Oliver Glasner is doing, we know it will be tough.

“It would be terribly presumptuous for us to assume we're already in the next round, that is not the way we do things. Tomorrow we need the head, the heart… and a bit of luck."
