Have to say I think you are correct.
Klopp knows that the league has gone or at best is very very unlikely and so needs something, or sees it as a better possibility than ECL or FAC, so has gone for the postponement.
As has been pointed out in other posts, we played the "kids" in this comp numerous times even when there wasnt a covid issue, so why not now?
I think there is only one real answer.
I think therefore it is only right is, as Liverpools "European Royalty" correspondent on earth, i now pass the banner and title of "Mentality Monsters" on to City.
The postponement is also in my view shortsighted from the fixtures POV. Fixture pile up isnt going to help anyone and top 4 should not be taken for granted. Spuds have games in hand and Conte has them motivated, Chelsea despite odd glitches grind out results and Arsenal are improving all the time.
