Alisson marked his Liverpool debut with a clean sheet as the Reds thrashed Napoli 5-0 in a friendly in Dublin
Alisson only had one serious save to make when he turned away Lorenzo Insigne's first-half attempt.
Liverpool scored through James Milner, Georginio Wijnaldum, Mohamed Salah, Daniel Sturridge and Alberto Moreno.
Midfielder Milner went off in the second half after an accidental clash of heads with Mario Rui.
He needed 15 stitches in what manager Jurgen Klopp described as a "crazy cut".
