Teenager Curtis Jones has grabbed a 58th-minute winner, as an injury-hit Liverpool qualified for the knockout stage of the Champions League with a 1-0 win over Ajax Amsterdam at Anfield.
The victory ensured top spot in Group D for Juergen Klopp's side with 12 points, after rivals Atalanta were held to a 1-1 draw at home to Midtjylland.
With seven points, Ajax are a point adrift of second-placed Atalanta and need victory over the Italians in their final group game to reach the last 16.
As well as Jones, Klopp had another youngster to thank for their win, as Ireland U21 goalkeeper Caoimhin Kelleher produced a vital save in the final stages of his Champions League debut.
Kelleher had been drafted in, after first choice Alisson Becker became the latest addition to Liverpool's long injury list, with a scan revealing a hamstring strain.
With Neco Williams at right back and Jones in midfield, Liverpool had a youthful feel, with experienced alternatives in short supply.
Jones rattled a shot against the post in the sixth minute, after being set up by Mohamed Salah, but Ajax fought their way into the game, with former Everton midfielder Davy Klaassen proving influential.
Kelleher was called into action in the 32nd minute, as he tipped over a blast from Noussair Mazraoui.
After the break, Klaassen missed a decent chance, heading wide at the near post, and the Dutch side should have gone ahead, when Kelleher had pushed out a Mazraoui effort and David Neres struck the post.
Then came the decisive moment - Ajax keeper Andre Onana badly misjudged a cross from Williams and allowed the ball to float over his head, where the 19-year-old Jones did well to guide it home at the back post.
Kelleher completed a memorable debut, when he pulled off a vital save in the final minutes to keep out a header from Ajax's veteran substitute Klaas-Jan Huntelaar
"It was an amazing one for me," says the Irish keeper. "To make my debut in a Champions League game was massive, and we got the win and qualified - a great night.
"That's what I'm there for. I work every day in training to make sure I am ready and I was able to make a good few saves."
Elsewhere, Manchester City played out a goalless draw in Portugal against Porto, while Real Madrid's progression past the group stage hangs in the balance, after a 2-0 loss to Shakhtar Donetsk.
