Bonatini scored his first goal since December, ending a 27-game barren run, as Wolves beat Sheffield Wednesday 2-0 in the Carabao Cup second round.
Nuno said: "It's very good. A goal is always a goal, it gives confidence to the player, but he has my confidence – that is more important.
"You know me...goal, important yes, he did a good job but it goes much further than that. It's about the team.
And Nuno was pleased to be reminded that he still hasn't conceded a goal in the Carabao Cup as Wolves boss: "Incredible! I didn't realise that.
"For us it was a good game. Every time a player wears the shirt of Wolves he knows what he has to do, he's inside of the shape and works very hard.
"I'm very happy with the answers and we'll work on our mistakes."
