Napoli coach Walter Mazzarri admitted to being excited ahead of his team's last Serie A home game of the season against Inter Milan tomorrow.
The southerners need only a point to ensure a top-three finish and a place in the UEFA Champions League group stages next season.
It would be the first time the club has qualified for the competition since the old European Cup changed format in 1992/93.
"Tomorrow will be a historic event because it's 21 years, since the time of [Diego] Maradona, that Napoli haven't been in the Champions League," he said.
"And if all together we manage to claim third place, it will put the seal on our season."
However, Mazzarri refused to commit himself to the club for the long-term, even though he still has two years left on his contract.
He has been linked with a move to bigger clubs but is rumoured to be wanting an improved deal in order to stay.
"Tomorrow at the San Paolo stadium we must be all together for a great party," he said. "At the end of the season I will meet with the club in a calm way and we'll talk about the future."
