Jurgen Klopp has praised Rhys Williams and Neco Williams for their recent contribution to a depleted Liverpool squad.
The academy graduates have had to fill in at the back with Trent Alexander-Arnold, Joe Gomez and Virgil van Dijk all sidelined with injury.
"Look, if somebody is a Liverpool youth or Academy player in general, he has already, for sure, a lot of talent – otherwise you can't make the cut," Klopp said ahead of Tuesday's clash with Ajax.
"When you then go through all these difficult moments in your youth academy career then you are already used to some difficult situations and some pressure.
"But when you come up and you make the final step and you have to play in a competitive game for the first team, that's a different animal.
"I think the boys adapted really well. They did a lot of really good stuff, helped us enormously, are very important – not only in the moment, but especially in the moment.
"The only problem they have from time to time is that people compare them with the guy who played the position before them.
"They are, in our case, all world-class players and that makes it maybe kind of difficult for people to see clear how talented these boys are. But from my point of view, they did really, really well."
