The striker did not get on the scoresheet for Juventus but put in a pivotal performance in the win at Trabzonspor, which left his boss delighted.
The striker complained earlier this week that he was being undeservedly left on the sidelines for the Bianconeri, but he was a key player in Turkey as he played a part in both goals to help the Serie A leader to a 2-0 win on the night and a 4-0 aggregate triumph.
"Giovinco did well with the assists, but he is right to get angry when he doesn't score," Conte told Sky Sport after the match. "He is a striker, so he should want to score goals.
"In order to continue winning in Serie A and the Europa League I need everyone to perform. Some of these lads are mistreated by the critics, but they can gain confidence and form by playing well in these games."
The Juve coach insisted that Sunday's visit to AC Milan was not playing on his mind when he formulated a gameplan to face Trabzonspor, despite fielding a number of second-string players.
"I am very happy because from the first minute of the first leg we played the game the right way," Conte added. "We did things as we had planned in this second leg.
"I had said before: I did not plan on coming here to just defend the 2-0 lead. I always play to win and to score goals, and not just think of Milan."
Juventus will face fellow Serie A side Fiorentina in the last 16 of the competition.
