Nigeria striker Osimhen scored either side of the half to avoid slip-ups in Napoli and help his side to a simple and deserved 5-0 aggregate victory.
Piotr Zielinski added Napoli’s third from the penalty spot on a perfect night for southern Italy’s biggest club, which Osimhen believes can go all the way.
“It’s amazing to make history with this win,” Osimhen told Amazon Prime.
“We will continue to dream, we have the team to do it (win the Champions League). I think we are on the right path. We have a great coach. We will see what the future holds for us, I think we have a good chance.”
Luciano Spalletti’s side are on the verge of securing their first Serie A title in more than three decades and an already remarkable season got even better with a place in Friday’s draw for the last eight of the best club competition in Europe.
They were propelled to an almost certain domestic triumph and a deep run in Europe by the fearsome Osimhen, who has now scored 23 times in all competitions for perhaps the continent’s most exciting team.
However, Spalletti was less optimistic about Napoli’s chances than Osimhen, answering with a curt ‘no’ when asked if he was flattered by Pep Guardiola saying his side were the best in Europe.
“It’s a game people play to put pressure on other teams, it’s a game everyone knows now,” an irritated Spalletti said.
Eintracht were without suspended French striker Randal Kolo Muani following his first-leg dismissal and the Bundesliga side did little to trouble Napoli.
Oliver Glasner’s side left the competition on a night in which their fans were embroiled in serious turmoil after traveling to Napoli despite no away fan tickets going on sale.
Eintracht had decided not to accept their ticket allocation for the match after Italian authorities produced two separate bans within days, fearing a repeat of the problems in Frankfurt ahead of the first leg.
That didn’t stop the German club’s die-hard fans, however, who clashed with local police on a tense evening in Naples.
Footage in Italian media on Tuesday also showed Napoli fans throwing objects at buses carrying Eintracht supporters.
Around the stadium, the atmosphere was less tense since Naples came out of it without a hitch.
Khvicha Kvaratskhelia nearly scored his second miracle goal in less than a week in the 19th minute after a brilliant tackle from Zielinski sent him charging towards the goal.
But he was forced away as he looked for a shooting opportunity and ended up being smartly denied by Kevin Trapp, who did well again two minutes before the break to keep the Georgian out.
However, Trapp could do nothing to stop Osimhen putting Napoli ahead moments later, with the Nigeria international showing why he is one of the highest rated strikers in the world with a perfectly timed jump and header. from the suspended center of Matteo Politano.
And Osimhen struck again seven minutes after the break with a simpler finish, this time tapping Giovanni Di Lorenzo’s low cross after another good play from Politano and Kvaratskhelia.
Napoli were cruising and, after two half chances for Eintracht’s Daichi Kamada and Rafael Borre and another good save from Trapp on Kvaratskhelia, they had three leads on the night.
The excellent Zielinski was knocked down by Djibril Sow, allowing the Polish midfielder to dust himself off and calmly score a free kick in the 64th minute.
All that was left was for the crowded Stadio Maradona to shout “Ole” on every pass as they watched their side go down in history.
