AH okay thanks, you think they can still beat Barca without him?
They would destroy Barca with him, but will still beat them without him.
This is a MUST win game because if they only win 2-1 or 1 goal win, they may very well be fucked at Nou Camp because they will have to play against the ref as well.
Pellegrini has seen enough of Barca and Messi during his time at La Liga plus, he will most likely rotate his players to hit Messi and play a bit dirty.
Plus City have the pace to handle the Barca midfield and full backs so really Barca is a bit screwed because they won't be dictating the pace of play.
Keys for City:
Dictate the pace
Be very physical with the midfield
Keep shooting, Barca D and goalie is not that good
Play for corners and set pieces
Keys for Barca:
Don't get too predictable
Don't walk into the goal
Control tempo
Minimize City's shot on goals
Keep the play in the middle of park
