That does not mean however that Klopp didn't rotate for Brighton, which he clearly did. How difficult is it for you to acknowledge that, whether you agree with it or not.
Hang on, surely nobody is saying that Klopp didn't rotate and rest players? He played three teenagers and two strikers who have played about 90 minutes all season and rested his best defender and first-choice keeper.
The obvious prioritisation of the league (regardless of who we're playing next) over the cup isn't up for argument.
