I'm forecasting that if we don't improve our xG numbers our results will definitely suffer.
Expecting our win rate to be lower than 75% seems only rational regardless of what Nuno does, so yeah, that will drop. By how much is the question. That will depend on performances ultimately.
I don't really do results predictions on individual games, because that's essentially impossible. Expected the City game to be though, but it came at a good time and we'd have a chance. Expected the Palace game to be difficult, but expected more from us going forward than we delivered in the first hour.
If we keep mostly creating chances on the break, if we keep being unable to break teams down and pay through real pressure we'll struggle.
