The Foxes were 2-0 ahead before Victor Osimhen struck twice to earn the point.
“The team started the right way, then lost the ball a few too many times building out from the back and those proved costly," Spalletti told Sky Italia.
“After that, we took the initiative throughout and it remained a perfectly balanced match. We reacted to conceding the second goal just as we were really pushing, and that was a risky situation, because we could've let our heads drop.
“Instead, we pushed even harder and got it back on level terms, because it frankly would've been unjust if we had lost this game.
“We saw today that this team has a strong character, which had been a weakness in previous years. The team reacted really well.
“I want to compliment those who came off the bench, because they proved their quality and it makes it easier for everyone, because they are not fighting to take the place of another teammate, but to play alongside him."
Spalletti added: “Osimhen still has a few things to learn and then he will become a super hitman. Comparisons are easy, but would be with some of the best forwards in the world.
“He needs to improve in the precision of his choices, both his finishing and the runs, because at times he runs for no reason."
