These are my afterthoughts on the match:
Liverpool didn't start with the high tempo pressing that put the games beyond City and Roma in earlier rounds, whether they were pacing themselves on the off chance of extra time or were just scared of being counter-attacked it seemed like they were playing within themselves.
Salah going off was massive, it looked like Ramos dragged him down and he had to fall awkwardly to potentionally stop the arm that was being held in some kind of arm lock from being broken.
Karius will never live that match down. Without his two massive errors you could say that Klopps tactics worked as Real didn't create much except when Liverpool were chasing.
