Well, we can't even think about this comparison until the season ends... If we're champions, it may be a fair question. If we're not, it dies right there.
For the record, in a one-off match, though I feel that this squad is fitter, tougher and stronger as a cumulative group of players, anybody who thinks that it'd be an easy win for Klopp's boys is loopy... Can you imagine a Barnes on TAA? Aldo on Lovren? Beardo buzzing around like he did, against our current back 4? Everybody not named Virgil would be torched at the back (though our FBs would also wreak havoc going forward).
I agree that 2019 would probably win it, but it might be 7-5 or some such nonsense. 🙂
