Jurgen Klopp told Liverpool's official website he was happy with Liverpool's performance against Bournemouth, and pleased with his youngsters.
Klopp believes Randall in particular will have learned something particular from the game, given plenty of practise from an aerial perspective.
The German boss said: "Connor Randall – all the long balls they played were in his space. If he was not a good header before this game, now he is much better! Because he had the chance to improve 20 or 30 times.
"I’m really fine with these guys. And, very importantly, the other players didn’t think because the manager did this it’s not such an important tournament. I saw in the eyes of all the players that they wanted to win tonight. That’s very important."
Randall played at right-back and featured for the entire 90 minutes. As Klopp points out, this is a game he can learn from to develop and improve, far more useful than dozens of under-21 games.
He showed he has the temperament to handle such an occasion, part of a back four which kept a clean sheet, and Klopp should not be nervous about having to throw him in again if he was out of alternative options.
