The last time the two teams met, Enzo Fernandez decided the result with the equalizer in the 90+4 minute at the Etihad stadium. But in this rematch, the Argentine midfielder was absent due to suspension. This is a decision showing that Chelsea's leadership is no longer patient with this vice-captain but also rebellious player.
Under coach Liam Rosenior, Chelsea continued to enter a period of instability. He became the ninth coach of the London team to face Pep Guardiola, while the continuous changes on the coaching bench clearly reflect the club's instability.
Not only is it a professional story, Fernandez has also become a symbol of the difference between the two development models.

Both Chelsea and Man City have been pumped with money to reach the top, but the operating methods are completely opposite. While Chelsea binds players with long-term contracts and is willing to spend heavily on young talents, Man City builds a stable system where stars are truly maximized in value.
Fernandez's ambition is towards Real Madrid, similar to Rodri's desire to be mentioned. However, Guardiola still maintains a clear view: players can leave if they feel unhappy, but must meet the value that the club offers.
I had a very good conversation with Enzo Fernandez. He apologized to me and the club, and we will resolve that issue after the important match this weekend.
This is a serious meeting about a very serious issue. Enzo Fernandez, on every step of the way, I have never doubted his personality or character.
I believe that everyone makes mistakes. But you cannot ignore punishment for that mistake. We have issued a penalty, I have made a decision. What I want for Enzo Fernandez is that he will continue to have an excellent career" - the Chelsea captain said.
The difference between the two teams is even more evident in investment efficiency. The Blues spent more than £1.6 billion under Todd Boehly but are still struggling in the rebuilding process. Expensive contracts like Fernandez (£107 million) or Moises Caicedo have not yet brought about a corresponding value.
Meanwhile, The Citizens only need about 101 million pounds to own the Rodri and Bernardo Silva duo - pillars that help them dominate English and European football.
Rodri has won many major titles, while Silva has become a leader on the field. Conversely, Fernandez - despite being the World Cup champion - has not yet been able to create a corresponding influence at Chelsea.

At the age of 25, Fernandez is no longer a young talent of the future. The Argentine international needs titles and a stable environment - something Chelsea has not been able to bring. Heavy defeats, typically the defeat to Paris Saint-Germain in the Champions League, further show the gap between ambition and reality.
Meanwhile, Man City still maintains the bravery of a champion. Despite entering the transition period, they are still competing for titles and maintaining a stable structure.
If there is a clear conclusion, it is that Chelsea is building a future with money but lacks a foundation, while Man City is maintaining its peak with a system. And in this confrontation, that difference may continue to be revealed.
