Liverpool boss Jurgen Klopp admits that youngster Tyler Morton "exploded" onto the scene after his display against Norwich City.
The 19-year-old has played in the Premier League and League Cup this term, and may make his Champions League debut against Porto in midweek.
Klopp believes that his debut against Norwich is when Morton got the self-confidence to show his true quality with the first team.
"I don't know what will happen tomorrow night but the progress from Tyler Morton has been pretty impressive," Klopp told reporters.
"Tyler had the full pre-season with us, you could see his technical skills but how well educated and how well behaved young people are.
"He was not overly confident, let me say it like that, he tried to adapt a little bit to what the first team were doing.
"It was good, not spectacular, but good and then we had the game against Norwich where he came on the second half and played a super game, to be honest, that made all the difference.
"You could see the next day how the confidence level exploded overnight and I saw for the first time – Pep [Lijnders] and Vitor [Matos] knew him before – the real Tyler Morton, 2021.
"Then he plays the Preston game, a really good performance, really mature and all these kind of things. That's how development with young players work, it's a really good example.
"We can speak a lot about these boys, we can let them train with us but let me say it like this.
"Bringing them on in a game in the right moment has the biggest impact from all the things you can do to help them, Tyler is a really good example of that.
"He is in a good place at the moment. Pretty sure he would give the same answer! Now, let's work from here."
