Arsenal won, therefore there will not be such a big scandal as after the Tottenham - Liverpool game, although in my opinion such a mistake has a greater impact on the outcome of the game than a counted or disallowed goal. Football has long since reached a level where a numerical majority means a lot (not like in hockey, but almost).
As for Holland, it makes sense to bet that he will score 2+ goals in the next game. For him it always happens at this pace - either nothing, or a hat trick.
Erling Haaland will get back to scoring ways, it is okay to feel like a big mess up. He lacked creative players to help with those passes.
Liverpool - Tottenham Hotspur shouldn't have ended in favor of Tottenham. That goal should have been ruled offside. Match officials can also be real biased. Tottenham Hotspur though, have won Manchester United, Liverpool and drawing with Arsenal. Sure they will get a win against Chelsea and draw to Manchester City.
Erling Haaland is undoubtedly one of the most prolific strikers in Europe but the fact that he's not been able to score in his last few games for Manchester City doesn't automatically mean that he'll definitely score two or goals in the club's next game.
Kelvin De Bruyne who assisted most of the Norwegian goals last season has been out injured since the first week of the English Premier League season and that has really affected Erling Haaland's goalscoring performance. There's no doubt that he can't score in next game but I there's no guarantee that he'll definitely score.
