Fernandez is among a group of players who feel their recent performances should prompt fresh conversations about a new deal.
The midfielder is now represented by a new football agency featuring former Paris Saint-Germain and Argentina player Javier Pastore, alongside established agent Matias Toranzo, following a split from his previous representatives.
Their main task has been to secure Fernandez an improved contract, and they have quickly made their intentions known to the club.
Since their appointment, there have been rumours that European champions PSG are interested, although the midfielder is known to be reluctant to move to the French club. Like almost every Latin player, he is known to admire Real Madrid but they are unlikely to make a move in the near future.
Asked about the speculation last week, boss Liam Rosenior said: “It means nothing to me. When you’re a world-class player, an outstanding player, there is always going to be speculation you cannot control. He has been outstanding in the time I’ve worked with him.”
Chelsea remain relaxed about any potential negotiations and have no intention to sell Fernandez even if there is interest. Fernandez is under contract until 2032, giving the club the option to reject approaches and providing significant leverage in any future renewal talks.
However, Fernandez is important to the club commercially and his image is particularly positive in the Spanish-speaking world, with sponsors often requesting his time in his role as a Chelsea player.
There is also no indication that the speculation or contract situation is affecting his performances. Fernandez recently played through illness – earning further praise from Rosenior – and has shown a willingness to cover for Palmer in the number 10 role or play deeper in midfield, with Romeo Lavia also sidelined.
Having been named vice-captain by former head coach Enzo Maresca, Fernandez’s personality complements the calm, understated demeanour of captain Reece James.
Those who know him describe him as an “aggressive leader” but also a little “loco” (crazy), and he is known to deliver team talks at half-time or around key matches.
Fernandez used Ukrainian performance coach Dima Chapovskyi to help adapt to the physicality of the Premier League, having had just six months in Portugal after leaving his native club River Plate in 2022.
He is also known to be into self-help books, has access to a psychologist and a personal coach that talks him through his clips on the pitch.
Along with Fernandez, fellow midfielder Caicedo and defender Levi Colwill are known to be keen for contract renewal talks, but Chelsea hope to park discussions until the summer with all three players.
