In fact, Manchester City is still performing well in the Champions League at the moment even without Kevin de Bruyne and managed to win the match against Leipzig, who are the strongest rivals in Group G, even though they have experienced 2 defeats in the Premier League this is really a shame, but I am sure Pep Guardiola wont only relying on Kevin de Bruyne, he still has several other key players, but we also don't know to what extent Manchester City will be able to survive without Kevin de Bruyne, but what is clear at the moment is that even though Manchester City has not appeared completely consistent, what is clear is that Pep Guardiola will soon fix things midfield at the club to be able to improve Manchester City current performance.
Pep Guardiola definitely has a backup strategy in carrying out this season in the Champions League and Premier League so that Manchester City can continue to appear strong in all competitions even though key players like Kevin de Bruyne cannot play as hard as they are currently. I am quite sure that Manchester City will not be weak enough this season because Pep Guardiola has a way of placing substitutes in midfield in order to continue to have a better defense and attack line.
The backup strategy was not going well like what it's planned. Manchester city lack of good attacking midfielders. The creativity of midfielders dropped so hard caused by city was losing some important players. There was still rodri but it's likely that if manchester city will not be playing like last season caused by the club was missing de bruyne. Rodri is good, but the club needs someone who can play as good as de bruyne. There has been speculation that Pep is considering purchasing Dani Olmo from Leipzig as a replacement for De Bruyne, however, I personally believe that this plan is quite far from becoming a reality.
There have been also many clubs linked to him. Despite the city's impressive achievement of winning the treble last season, the probability of them obtaining Olmo remains quite small.
Pep needs also to prepare another plan for the team. Haaland can't do that alone. I know that haaland is a great striker, but it's impossible to see him play like last season without someone who was helping him like de bruyne.
De bruyne was consistently assisting him last season. Haaland is struggling to score against the opponent. We are still more than 1 month away from the winter transfer window.
