Unfortunately I was unable to see it, but I did hear that Poch matched Chelsea's formation. However it does seem that the high pressing from Kane, Alli and Eriksen unsettled Chelsea and that is something we are good at. I wouldn't expect to see Klopp alter much, but I don't necessarily think the formations need to be matched to achieve the same result. I think style is much more important than formation.
In a way you could argue that at time we would resemble a 3-4-3, with Henderson dropping between the CB's, fullbacks pushing up and wingers tucking inside. Not that I'd want Henderson man-marking Costa, even if he can stare him down
