Lazio blew a 2-0 lead in Turin, but Sarri was still happy with the performance.
He stated afterwards: "It was clear that Juve could come back from 2-1 down. They're a more physical team than us, and we struggled with the balls in the box for months.
"The biggest disappointment is that we had clear chances to make it 3-1 and take the match. This leaves a bitter taste in our mouths.
"Ultimately, I must be satisfied with having a team that, despite a thousand difficulties, doesn't give up. It means that the morale in the locker room is high, and that gives me satisfaction."
Sarri added: "Danilo (Cataldi) is a player who lacks a bit of drive to be a top-level player. (Daniel) Maldini did some good things; maybe he didn't shoot much, but he put his teammates in a position to be dangerous.
"He's integrating quite well."
