The Italy forward marked his debut appearance at Anfield for the Reds with the opener - a clinical first-time volley - in a 3-0 success over the Belarusian side to help Brendan Rodgers' charges book a place in the Europa League play-offs.
"It was absolutely a day to remember," he told Liverpoolfc.com. "The fans were amazing and the atmosphere was unbelievable, just for a Europa League qualifier. To also get a goal was amazing.
"It felt like it was the first goal I had scored in my entire career. I tried to celebrate as I did for my first goal in Serie A."
He added: "Since I signed, I've wanted to score my first goal as soon as possible. I got my first here at Anfield, which was very nice, and now I will carry on working.
"The goal will help me continue to settle in - goals always help."
