Lukaku scored on Friday evening in the victory over Cagliari to confirm Napoli as Serie A title winners.
He said at the last whistle: “I now feel so many emotions. I have moved for the team and these players, we worked so hard, but we did it and that is the most important thing.
“We all won, I was only a small part of this team. We only thought of the team, everyone was important, whether they were playing regularly or not, that's how we took it home.”
On the influence of Antonio Conte Lukaku continued: “I knew what the coach was capable of and thought from the start that we could do something important.
“We proved our maturity, showed improvement and after the game at home at Inter I thought we really have a big chance to win.”
