Alvarez shocked Los Rojiblancos during the 2026 FIFA World Cup after declaring his intention to leave Madrid to join LaLiga rivals Barcelona.
Atleti consistently maintained their position over not wanting selling Alvarez to the defending Spanish champions after a furious war of words between the two clubs and he remains in place in the Spanish capital.
After telling Barca there was a '0% chance' of signing the Argentinian, Arsenal were linked with an offer, but no formal bid emerged as Alvarez was unconvinced over a return to the Premier League.
The 26-year-old still wants to move on and believes a new agent can help him do that in 2027 - as per reports from Mundo Deportivo.
Alvarez has been represented by Fernando Hidalgo throughout his entire career, but he's rumoured to be in talks with The Elegant Game - an agency run by former player Javier Pastore - which also represents Enzo Fernandez.
Atleti officials criticised Hidalgo for his conduct during the transfer saga, and with Alvarez also unhappy with the end result, a change in direction could be incoming.
