He joined a new agency founded by former Argentina star Javier Pastore, according to the site "CaughtOffside."
This change has sparked speculation about the player's future at the English club, especially given the agency's strong connections with clubs in Italy and Spain.
The move to change agents aims to develop his career and increase global visibility, but it has reopened discussions about a possible departure from Chelsea. Despite no official offers so far, major clubs have been monitoring the player's situation since last summer.
Fernandez joined Chelsea in January 2023 for £106.8 million after a successful season with Benfica and a prominent role in Argentina's 2022 World Cup victory.
Chelsea coach Maresca has used Fernandez in various midfield roles, while the player prefers a more advanced position with free movement, which he has not consistently achieved. This difference has contributed to rising speculation about his future with the club.
