City need to beat Brugge and they have to do it because it will allow them to overtake Brugge in the table and not depend on the result of other games.
Manchester City will advance to knockout phase play-offs if they win and they will be eliminated if they lose.
Whatever happens in other matches will not matter to Manchester City.
Between the two options of winning or losing because if the draw is no longer hopeless, then the match against Club Brugge should be able to win at home.
I think Pep Guardiola should focus on this match first because it concerns them in order to qualify for the playoff phase, maybe in this match they can win at home, if for example they lose then it means that Manchester City's ability is still below.
