i think if they go 4-2-3-1 and the midfield is lucas merieles and gerrard amc, liverpool have a chance, because that will put gerrard one on one with mikel, and gerrard is more likely to win that battle on current form, so it will drag essien back giving lucas and merieles space to work into. if poulsen plays liverpool are in trouble, they really need a mobile midfield against chelsea
