Gundogan and De Bruyne were among Manchester City's best players last season. And with the help of these two players, Manchester City scored a lot last season. Haaland was also in top form. With the midfield strong, City's attacking players also did very well. Gundogan is not with the squad this season. Also De Bruyne is out of the squad due to injury. So naturally, Manchester City's performance is a bit slow this season.
Yes that is quite true indeed, De Bruyne's injury was an unexpected one but well that is what have lead to a strong attacking midfield linkup and it is affecting City's performance. Still they have some quite some players in midfield but not close to fill De Bruyne's boot completely.
Haaland scored 9 goals in 9 matches this season. However, City's midfield is still weak. City can play well because of Guardiola's excellent match strategy. Guardiola is rumored to be interested in adding Toni Kroos to his squad. If Kross joins the City squad then I think Manches City will be strong again.
About this, the question is does Kroos also plans to leave Real Madrid and join Manchester City? I don't think so. I think he is gonna stay a while at Madrid no matter what offers are on his table. Although it will be quite good to have midfield maestro in the squad but I feel like Kroos to City if is true will be a hard one. It is also possible that Madrid might not plan to let him go.
