This comment was also shared on social media, and soon after, Atletico's coach Diego Simeone reached out to Alvarez to discuss the possibility of him joining the team. Alvarez was also spoken to by other players, including Rodri and Antoine Griezmann, with whom he had spent the day.

As Alvarez continued to consider the offer, Griezmann played a key role in convincing him to join Atletico. Griezmann, a legend at the club, sent Alvarez a message on Instagram and later on WhatsApp, encouraging him to join the team and promising him a good experience with the fans.

Alvarez has said that Griezmann's message was a significant factor in his decision-making process. The combination of Griezmann's endorsement and the other factors that came into play eventually made him decide to join Atletico Madrid.
