Julian Alvarez wants out of Atletico Madrid, and now he has one of the most famous strikers in Argentine football history publicly cheering him on.

Sergio Aguero made his stance clear on June 23, endorsing Alvarez’s transfer request and arguing that the 24-year-old would slot seamlessly into Barcelona’s system. Aguero made the remarks on the Jijantes FC streaming show, giving the saga the kind of high-profile co-sign that tends to accelerate these things.

Alvarez publicly acknowledged that he had requested a transfer from Atletico following internal discussions with the club, a move that confirms the relationship between player and club has reached a breaking point.

What Aguero actually said

Aguero described Alvarez as a top-class player capable of operating anywhere across the attacking third.

Aguero also floated the idea that any potential deal could be structured with installment payments spread over five or six years. That framing is a nod toward Barcelona’s well-documented financial constraints, which have made straightforward large-fee transfers complicated in recent years.

The Atletico complication

Atletico Madrid previously rejected a €150 million offer from Real Madrid for Alvarez, which tells you two things simultaneously.

First, Atletico values Alvarez extremely highly and is not inclined to sell cheaply. Second, Barcelona would need to match or exceed that figure to have any realistic conversation with Diego Simeone’s club, which creates an obvious tension given Barcelona’s financial situation.

Alvarez originally moved to Atletico from Manchester City in 2024 for approximately $110 million. A club paying that kind of fee rarely lets a player walk after one or two seasons without extracting a meaningful profit.

The fact that Real Madrid’s €150 million offer was turned down suggests Atletico’s asking price sits even higher, or that the club simply had no interest in strengthening a direct title rival regardless of the number.

What this means for Barcelona and the broader transfer picture

The challenge is the math. Barcelona’s financial constraints are not a secret, and they have had to be creative with deals in recent windows, relying on deferred payments, performance clauses, and other structures that spread costs across multiple fiscal years. Aguero’s suggestion about installment payments is less a random idea and more a reflection of how any Barcelona deal for a player at this price point would realistically be constructed.

The broader post-2026 World Cup transfer window adds another layer of complexity. Players who performed well at the tournament tend to see their valuations spike, and clubs negotiating in the weeks immediately after the World Cup are often doing so at the peak of market pricing.
