Agree.
On the flip side, Liverpool also played tonight, and they have United at home next week.
On the plus side, the siege mentality, and the will to avoid defeat tonight will do us no harm.
I think it depends on what team Klopp picks. If he truly wants the quadruple, he will play as much of his 1st team as he can, and maybe risk United next week. If he wants the PL title more, he will use his squad players, just like Pep will.
I hope I’m wrong, but I also think Liverpool will edge the game, sadly.
