Erling Haaland is starting to have difficulty scoring goals because De Bruyne's performance may have declined slightly, resulting in the flow of the ball for Erling Haaland stopping. But when facing West Ham, he managed to score two goals for Man City's victory and hopefully this will be a turning point for him and the team.
Manchester city is too big of a club to be depending on only one player to be supplying the ball to the goal scorers, I thought they had Phil Foden that could give assists and other players too. What I think happened was just Pep Guardiola losing control of his creative mind and there was nothing new that he could coach the players on and this cause the whole bad form that the club was on as you can't say it was only De Bruyne absence that cause the decline in the club. Some individual say it's the absence of Rodri that's causing the club to be in bad form therefore everybody has their own theory but atleast all that will be over soon as the players are regaining their form.
Actually I do not think that Manchester city are depending on one player as speculated, rather it's seems to me that the squad is in need of back up players because it obvious that when all these injury worries started at Manchester city there were no viable or suitable back up players in the the team and that was why the vacuum that Rodri left became so visible.
If the likes of kovacic were playing the way they Rodri was doing then no one would have noticed Rodri's absence, hence this goes to show how important it is for the coach to shop for more players in certain areas of the team, like the defensive area, the midfield and defensive midfield too, at least to help fortify the squad for the second half of the season.
