A matchball was just reward for a wonderful display in which Silva linked up with Hakan Calhanoglu and Nikola Kalinic, with Montella suggesting the victory would do the forward a great deal of good.
"Andre Silva was hungry and he got his goals," he told Sky Sport Italia . "These are different games than in Serie A and so he was allowed to take advantage of his ability to attack space against a defence that was playing a high line.
"This performance and these goals will undoubtedly give him more confidence - he really needed it."
And Montella also had words of praise for Calhanoglu, who created two of Silva's three goals as well as scoring the opener himself in the 5-1 success.
He added: "Calhanoglu showed great quality besides his goal. He created goals for his strikers and he moved forward really well."
