One of the key aspects of Fernandez's game is his ability to make runs into the opposition's box. He has made 15 such runs in the first three Premier League games, which is the highest number among his teammates. He has also had a high xG (expected goals) of 3.75 in his seven appearances, indicating that he is getting into the right positions to score goals.

Fernandez has been leading Chelsea in both goals and assists since January, with a total of 19 goal contributions. His close-range strike against West Ham in a 5-1 win showcased his ability to finish chances. He has also been praised for his leadership qualities, particularly by Argentina manager Lionel Scaloni, who has noted that Fernandez's leadership has developed since joining Chelsea.

With Chelsea's squad consisting of players with a low average age of 23.2 years, Fernandez's experience and leadership are crucial. He has played a key role in Argentina's 2022 World Cup win and has been handed the captain's armband by his teammates. While there have been reports linking him with a move to Real Madrid next summer, it seems unlikely that the Spanish giants would be willing to pay the required fee.

For now, Fernandez remains an undisputed key player for Maresca's side. The investment made by Chelsea in January 2023 seems justified, and both the player and the club will want to continue this momentum.
