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.
Last season, De Bruyne's absence made Man City's performance decline and Erling Haaland also couldn't do much because he was a striker who had to be supported by other players to be able to score goals and after KDB returned, Erling Haaland showed his sharpness again and his club's performance slowly started to improve and this season almost the same thing happened to Man City who lost Rodri and made Man City's performance decline a little drastically from before and KDB also couldn't help Erling Halaand to score goals, I think Pep Guardiola needs to bring in players who can help Erling Haaland KDB is old and Rodri is still out for quite a long time so Man City needs a midfielder to fill Rodri's void.
