Liverpool's kids are most certainly alright.
To a man - or perhaps more accurately, for some, boy - those in red were largely in control and dominant against Shrewsbury's seniors, winning their physical battles admirably and making the most of their superior technical ability.
Unlike in the initial FA Cup tie, in which some senior stars like Dejan Lovren, Joel Matip and Fabinho featured, this looked like a Liverpool side, despite it's youth, wholesale changes and lack of household names.
Only James Milner was present at Anfield of those first team stars, with most having made the most of their winter break by jetting of around the world in search of the sun, and he was only sat in the stands.
On a sensational night for Liverpool, it's Academy and all of the backroom staff and coaches, our post-game podcast contributors gave their verdicts - and they make for excellent reading.
Ross Strachan, Widnes
The kids got the job done tonight and it was nothing more than they deserved. The magnificent season we're having just gets better and better.
No manager, no Klopp, I had my doubts about it. But why did we even worry? From front to back, the effort they put in... they were absolutely brilliant.
It was an absolute pleasure to watch.
Curtis Jones - some player he's going to be. The more I see him, the more I like him. Technical ability, invention, goal threat. He's got that swagger and he's even doing little rabona kicks - for a 19-year-old kid, you don't see that.
If he was Brazilian, Spanish, Argentinean, there would be absolute rave reviews about him. He's a special, special player; he's top-class.
Harvey Elliott, Pedro Chirivella: I could go through every single one of them really.
I thought the Reds might have tired a little bit in the last 20 minutes, but it was actually the last 20 minutes when we grew even more into the game and that's when we got the goal.
It came from Neco Williams, who was surely man of the match there, brilliant down the right-hand side. He could have had three or four goals.
A wonderful night for the club and the young lads involved. It was a pleasure to be involved in it. Hopefully we see some of these young lads getting minutes in the Premier League.
Sam Planche, Maghull
It was absolutely great for the kids to get a chance. But I must admit, I didn't expect us to win the game.
The full focus is on the league this year. You don't want to go out of any competition but still, the league has to come first. I know what Klopp's point is: he's told the team they can have a holiday and then he can't go against that.
It's like in any work: once you've told your team something, you've got to be held to that.
I really have seen everything now with Liverpool. I've been surprised tonight. I didn't think we'd win. I know that lads have got ability - especially Harvey Elliott and Curtis Jones - but I thought Shrewsbury would have a bit more know-how.
The goalkeeper and centre-halves - they always take longer to develop - and I thought they might 'let us down', but they were brilliant.
To come here with a third string side and do that is phenomenal. But the big point for me is that this is the mentality of the club. They play the same way, they have the same belief.
James Milner being there epitomises that. Just behind the bench and he's been in the dressing room. The togetherness that the players have at all levels is great and this is why we're building the Academy into a training ground for all ages at the club.
You've got have a load of ingredients and when it comes together - and we've got every right - it's brilliant. I don't care what the betting people say - we were underdogs tonight. I didn't think we were going to win the game and we did.
