At this point in time beating Man City isn't something clubs should see as a thing to brag about because the club is not so strong unlike when they have not started encountering this their problems and the team was still complete and confident.
These days what I've observed about City is that whenever they play and they score first, Guardiola doesn't get excited because he knows the game could turn on its head so he chooses instead to bite his nails and pace till the game is over then he'd celebrate so I expect much of that pacing, panicking and plenty of water drinking today as the game unfolds.
