Insigne struck in the 3-1 victory on Monday.
"The season has started off on the right foot,” Fabio Andreotti told Radio Kiss Kiss.
“Besides the goal, I loved the two assists. I’m also happy that Benitez has made Insigne the second penalty taker.
“With Benitez the attackers are tasked with attacking, however, with [former Coach Walter] Mazzarri the attackers had a lot of defensive work to do.”
