To add...
On Betfair we are 6.4 to back and 7.6 to lay which, taking the middle ground, makes us about 6/1 again. That equates to a 14% chance, give or take.

What really jumps out is how the markets give both Fulham and Brentford almost no chance at all relative to us.
FiveThirtyEight put it at 25%, which is a lower forecast probability than before Liverpool remembered how to play football.
