Conte made his comeback after the four-month ban expired and was shouting from the bench during the 1-0 win in Palermo.
Gigi Buffon said: "Conte's presence is very important, even before kick-off. He ensures nobody can step on to the field lacking concentration or motivation. That's practically impossible with Antonio!
"We should've been more incisive with our attacks today, but winning is what counts and we achieved that.
"The conditions were not helpful. Believe me, it is not as easy as it looks to be a goalkeeper in the rain when there are very few scoring opportunities, as you have to stay sharp."
