Manchester City striker Julián Álvarez is Atlético Madrid's first choice to replace Álvaro Morata should the Spain captain join AC Milan this summer, sources have told ESPN.

Álvarez, 24, has scored 36 goals in 103 games since joining the Premier League champions in the summer of 2022 from River Plate but has failed to break into the starting XI because of Erling Haaland's presence.

A 2022 World Cup winner with Argentina and newly crowned Copa América champion, Álvarez was recently questioned about his future and though he insisted he is happy at City, he also added: "We shall see."

Álvarez wants more playing time and Atlético are happy to make him one of the pillars of coach Diego Simeone's new project. As ESPN has reported, Atlético have considered different alternatives to strengthen their attacking line after the club announced the departure of Netherlands forward Memphis Depay.

Girona's Artem Dovbyk and Villarreal's Alexander Sørloth are among the players that the Rojiblancos have monitored in recent months.

However, sources have told ESPN that Atlético are willing to make a financial effort to sign Álvarez if Morata leaves the club this summer. Other sources have confirmed to ESPN that Morata has already agreed personal terms with Milan but is yet to formally sign.

Morata's future at Atlético has been in doubt in recent weeks with reports that the former Chelsea forward was close to joining Saudi Pro League side Al Qadsiah. Morata, 31, turned down the offer and declared his love for Atlético on social media. However, sources have told ESPN that Morata has now decided to leave and continue his career at AC Milan.

Sources have also told ESPN that Atlético have not been informed of that decision but the Spanish club is aware that AC Milan can get Morata if they meet the player's 15m ($16m) release clause.

Although Atlético could make room for forward Samu Omorodion, who impressed while on a season-long loan at Deportivo Alavés, Simeone has chosen Álvarez as the ideal No. 9 to lead the attack.

The next few days will be crucial for Morata's future. Once it is decided that Morata will leave, the Rojiblancos will activate a plan to try to sign Alvarez. Morata, meanwhile, left a message on social media regarding his intentions when answering a fan that criticised him for his potential departure from Atlético.

"Now I cannot leave and yet after [the Champions League quarterfinal defeat to Borussia] Dortmund, you all wanted me out," he wrote and then deleted.

Morata, who played two seasons on loan at Juventus from Atlético before returning in the summer of 2022, recently complained that he received no respect from the media and fans in Spain.
