Never happen. But the question of how LCFC fans would feel if it did is nevertheless an interesting one.
For me, the big six cabal is so utterly corrupt and reprehensible that any personal animus I have for a derby enemy is trumped by the glee I would feel at seeing the cabal's helpless rage at having their private club violated for the second time in a decade. Again, never happen - but I'd love it if it did.
