The Reds were in the draw for the next round after their 2-2 draw against Wolves on Saturday, but will only be sure of their fate in over a week’s time.
And if Liverpool secure victory against Julen Lopetegui’s side to continue their title defence, they will make the trip to Brighton in the next round after the draw was made on Sunday.
When is the fourth round?
The potential match against Brighton at the AMEX will take place over the weekend of January 27-30 and is, as always, subject to television selection.
How about the third-round replay?
Liverpool’s replay at Wolves is expected to be scheduled for either Tuesday, January 17 or Wednesday, January 18.
