Napoli coach Luciano Spalletti was delighted with their 3-0 Champions League win against Eintracht Frankfurt.
It means the Azzurri reach the quarterfinals 5-0 on aggregate.
It is a great result, we are going to enjoy it along with all our fans," Spalletti said afterwards.
Now it becomes fundamental that we maintain the same attitude we had this evening, because we didn't have the same quality as usual at the start, but we still executed the moves well and allowed very little to the opposition. We kept clear heads.
If Napoli in the entire history of this club had not reached the quarter-finals before, that means this is a great result."
Osimhen scored a brace and was named Man of the Match.
He is an excellent striker who can be a bit of a soloist and makes these sudden surges, but he also has to combine with the rest of the team. He is starting to do that now and we are very happy."
Spalletti, meanwhile, dismissed claims from Manchester City boss Pep Guardiola that Napoli were the best team in Europe.
I don't feel proud, I don't feel anything. I know this game that everyone does to put pressure on the others. Are we putting Napoli in front of Manchester City? If they can spend 900m compared to our 9m, there must be a reason. It's a game to build us up so they can knock us down."
