Really hope we don't go there with the same mentality as we did in the league game. Unlikely to get away with it twice.
Looks like they will be without their two best players in Coutinho and Salah. If there's ever a time to go there and be positive, it's now. 8000 blues, Friday night, cup competition, expected to get beat and nothing to lose.
That's what I'd go with. 4-2-3-1/ 4-5-1.
