Curtis Jones struck the winner as Liverpool booked a spot in the Champions League Last 16 with a narrow 1-0 victory over Ajax at Anfield.
The 19-year-old midfielder hooked home just shy of the hour after an error from visiting stopper Andre Onana.
It was ironic to see a mistake from the most experienced goalkeeper on the pitch after the Reds were dealt a pre-match blow with the news their first-choice goalkeeper Alisson was out with a minor hamstring problem.
Jurgen Klopp turned to rookie keeper Caoimhin Kelleher, who gave an excellent account of himself on just his fifth first-team appearance for the club.
Jones hit the post early on as both sides looked to attack in what was a lively but goalless first period.
Ajax dominated after the restart but couldn’t make it count. Davy Klaassen headed wide before David Neres hit the woodwork on the follow-up after Kelleher had denied Noussair Mazraoui.
