There are some rumors about players who will replace Rodri, whether it's just a temporary loan or a permanent purchase, we'll see who Man City will bring in this January transfer market because this club really needs a midfielder who is productive in providing passes. Man City needs improvement in order to return to their best performance not only in the EPL but also in the UCL because usually Man City is a strong candidate in the UCL so it would be a shame if Pep Guardiola is unable to bring Man City to qualify for the next round.
The problem is finding players who can be productive enough in terms of providing passes from the midfielder position in the transfer market is always not easy and even if there are players like that, they will not be the same as the quality that Rodri already has. So Manchester City also have to polish other players to be better so that some other players can also contribute in making classy passes to their front line players. Because if Manchester City cannot change this in the rest of this season, of course Manchester City will not be able to go far in the Champions League and also in the EPL this season.
Losing Rodri has really undermined the greatness that manchester city has had so far, their desire to continue to dominate the English league and UCL finally had to fail after the bad luck that befell them against Arsenal in the early season match, now the transfer market has opened and manchester city has tried to recruit several players who are considered capable of having a positive impact on their current performance, in my opinion, Guardiola previous mistake was the minimal rotation of players he did, so that when they get problems such as losing Rodri at this time there is no appropriate replacement to replace him, if we talk about the chances of winning in the EPL and UCL, actually their opportunities are wider open in the UCL this season than the EPL.
From your explanation it is very easy to conclude that Rodri has been the player that has been carrying Manchester City in his shoulders because the last time I checked Rodri didn't play all the matches in the times where Manchester City won or their trophies but they were incredible in their performance. Now the performance of Manchester City has greatly declined and the team is struggling to get back to good form, regardless of the situation that has affected Manchester City right now I think they need to work on their performance while they awaits the return of Rodri this is because even though Rodri comes out of injury now he may not perform well like before because most of the players of Manchester City are in poor form especially Haaland their goal getter.
Manchester City does not have the chances of winning any major trophies this season looking at their position in the domestic league, Liverpool is already favorite in the league and the champions League competition is another place where there are better teams eyeing the champions league trophy, Liverpool team is one of them cause they have the best performance so far.
