Losing De Bruyne indeed have an impact for Manchester City performance in Premier league and it proven Haaland performance looks decline when Manchester City playing without De Bruyne but in this competition i am sure Manchester City will be qualified with champion group status
Yes, to be able to win the title you need talented player and Haaland cannot face thats alone without player who strengthen the defense line, and so far Kevin De Bruyne has done his best for Manchester City if Pep Guardiola doesn't immediately make a mature strategy It is not impossible thats Manchester City will have difficulty facing the Premier League and also the Champions League.
therefore Pep Guardiola only hope at the moments is for Haaland to be able to scored goals for Manchester City, but this all requires strongs team collaboration to be able to achieve victory in every matches.
I don't think Manchester City has a lost a lot,sure their recent results suggest that they are not doing well but any team can happen to have a bad moment and that is exactly what Manchester City is experiencing right now.The good thing for them was this International break which will help them recover both in Premier League and in Champions League where they should have no problems at all passing the group stage.
For the long term though I agree they need someone to replace De Bryne if he will continue injured and even when he recovers his performance would need time to match his performance before he got injured.
Manchester City have lost two matches in the Premier League. However, the team continued to dominate the Champions League. They have won easily in both the Champions League matches. But we have to accept that Manchester City's performance has deteriorated somewhat. Their midfield is somewhat weak except for De Bruyne. De Bruyne is one of Manchester City's most important players. So it is not possible to fill De Bruyne's vacancy for coach Guardiola. However, Guardiola is a very experienced coach. Manchester City is still consistently doing well because of his excellent match strategy. Also because the understanding between City players is very good. This is why City's performance is still somewhat stable without De Bruyne.
