The Azzurri steamrolled Juve on Friday night.
“It's a wonderful night because the team played really well and kept the tempo high, which is what we need to do, and above all the crowd provided a great atmosphere," Spalletti told DAZN.
“This team knew how to recreate the sense of love the fans have towards the club and played in the right way today, so if they do what is within their capabilities, they can play the way they did tonight.
“We stayed in the game in the right way after Juve scored and the fans helped us to deal with that moment when Juventus reacted strongly, creating some problems including that Di Maria goal.
“If we try to go into these duels, the way we did on the goal, we will lose them most of the time, because it's just not in our nature, those are not our characteristics. So we need to play the ball. Our DNA is to play like this."
He also said: “(Victor) Osimhen is such a great striker. I am stunned by the unexpressed potential he has and excited to see what he'll do in future. There were these two or three balls down the touchline and he has the pace, the skill, the courage and physicality to deal with those situations.
“After all, he smashed his face a couple of times because he goes for every ball. He still has remarkable room for improvement."
