Rodri and De Bruyne seem to be out for quite a while based on my reference sources, but City still have other players to replace them. They have Silva, Kovacic and Gundohan, or Foden who will be rotated. There are still other names for Pep to formulate his strategy against Newcastle in tomorrow's match. Moreover, even though they are playing away and some of their main players are absent, City are still far superior to the home team. It is clear that City's chances of getting points in this match are very big. But it's not football if the results can be predicted or known for sure, when the match is running in normal time anything can happen. Perhaps, Eddie Howe will formulate his tactics based on the City vs Arsenal match. Nothing is impossible, although theoretically City is always favored. We'll just have to see when this match is held, hopefully Newcastle will put up a fierce fight so that the match is worth enjoying when we watch it.
Rodri and Kevin De Bruyne being ruled out of City's games due to injury is really very sad especially for Rodri who could be out for a very long time until the end of the season as a result of how severe his knee injury he sustained in the match against Arsenal last sunday is, but that not withstanding Pep Guardiola can find suitable replacement from his squad and they move on so i don't see much threat to Manchester city in their upcoming match against Newcastle. I know Newcastle can be a stubborn opponent but Manchester city will try their possible best to record victory and still continue their campaign at the top of the league table.
If one were to discuss Manchester City's most important players, I think the first names that would come to mind would be KBD and Rodri. These two players are Manchester City's attacking midfielders as well as the great finishers the team needs at times, but unfortunately both players have suffered long-term injuries at the same time this season which has led to concerns over their injury management.
KBD was most likely out of action last season too with an injury and was expected to make a strong comeback in the upcoming season but failed to do so. Since two important players of the team are not with the team at the moment, Manchester City will hire new players instead of these two or they will continue this season with their old players, but it is not yet clear from the team.
But if there is a weakness in the performance of the team then I think definitely some players should be brought to the club even if on loan.
