Maresca praises Fernandez for his progress since joining Chelsea. He feels that Fernandez has been doing well both on and off the pitch.

Initially, Fernandez found it challenging to adapt to Chelsea's playing style at the beginning of the season. However, he has made significant improvements and is now contributing greatly to the team with his goals and assists.

Maresca prefers a balanced team where multiple players contribute significantly, rather than relying on a single player to score all the goals. He believes that Fernandez's contributions this season have been exceptional and that he will only continue to improve in the next season.
