The Corkman kept a clean sheet in his European debut.
Cork goalkeeper Caoimhin Kelleher was the star of the show as Liverpool qualified for the knockout stage of the Champions League.
Kelleher made a number of saves, including a late stop from Klaas-Jan Huntelaar as the Reds beat Ajax 1-0 Anfield.
Curtis Jones scored the only goal of the game in the second half.
The win means Liverpool are guaranteed top spot in Group D.
That's because Atalanta followed up their win at Anfield with a 1-1 draw with Midtylland.
22 year old Kelleher says it was a special night.
Manager Jurgen Klopp praised Kelleher's contribution.
Regular goalkeeper Alisson has a hamstring injury, so Kelleher may also make his Premier League debut against Wolves this weekend.
