Julio Diaz in 2026: Net Worth and Salary, Height, Age, Stats, Transfer Values, and FAQs

Early Life and Background

Julio Diaz del Romo was born on January 10, 2005, in San Fernando de Henares, a town just east of Madrid. He grew up in the Community of Madrid, and football was part of his life from a very young age. He started out at Rayo Vallecano's youth setup before making the switch to Atletico Madrid's academy in 2018, when he was around 13 years old. That move to Atletico turned out to be a turning point for his development.

At Atletico, Diaz worked his way through the age groups. He played for the U15s, then the U17 B team, and eventually joined the U19 squad, known as Juvenil A. He was not the flashiest name in the academy, but coaches noticed his consistency, his willingness to get forward from the left back position, and his solid defensive awareness. He was the kind of player who did his job and kept improving season after season.

Career Stats and Highlights

One of the biggest early moments in Julio Diaz's career came during the 2022 to 2023 UEFA Youth League. Playing for Atletico's U19 team, he was voted the second best player during the group stage of the competition. That kind of recognition at the European youth level is not something many young left backs get, and it put him on the radar of scouts beyond Spain.

In the 2023 to 2024 season, Diaz was a key part of the Atletico Juvenil A squad that won the Division de Honor Juvenil title. He was a regular starter and contributed both defensively and going forward. After that title win, he moved up to Atletico Madrileno, the club's reserve team competing in the Primera Federacion, which is the third tier of Spanish football.

With the reserve team during the 2024 to 2025 and 2025 to 2026 seasons, Diaz continued to develop. He scored his first goal for Atletico Madrileno in April 2025 and racked up around 50 appearances across all competitions. He was one of the most consistent performers in that squad, playing regularly and earning a jersey number 34.

The big breakthrough came on February 28, 2026, when Julio Diaz made his official debut for the Atletico Madrid first team in a La Liga match. He started the game at the Estadio Carlos Tartiere and played the full 90 minutes in a 0 to 1 away victory. Atletico themselves celebrated the moment, describing him as one of the reserve team's most consistent players, valued for his quality and versatility.

Transfer Values

As of early 2026, Julio Diaz's market value on major football databases was estimated at around 1.5 million euros. His transfer value had been climbing steadily as he gained more experience with the reserve team and made his La Liga debut.

On July 28, 2026, Sevilla FC announced the signing of Julio Diaz from Atletico Madrid. The deal was structured in a way where Diaz moved without a direct transfer fee, but Atletico Madrid retained 50 percent of his future rights, meaning they could potentially benefit from any future sale or even bring him back. Diaz signed a contract with Sevilla running until June 30, 2031, which is a five year deal. He reportedly chose Sevilla over Levante, who were also in advanced talks with him.

For a 21 year old left back with La Liga experience and youth international caps, this kind of move makes sense. Sevilla has a strong history of developing young talent, and the club is giving him a chance to establish himself in the top flight.

Net Worth and Salary

Julio Diaz's exact salary details have not been publicly disclosed in full, but based on available information, his weekly wages at Atletico Madrileno were reported to be around 567 pounds per week. That figure is typical for a reserve team player at a major club.

With his move to Sevilla FC's first team squad, it is reasonable to expect a significant increase in his earnings. Icon Polls estimates that Julio Diaz's net worth in 2026 is between 500,000 and 1 million dollars. This estimate takes into account his earnings from club contracts, bonuses, and potential endorsements. As his career progresses and he gets more playing time in La Liga, that figure will likely grow.

It is worth noting that at 21 years old, Diaz is still at the early stage of his professional career financially. Players in his position typically see their earnings rise sharply if they become regular starters in a top European league.

Height, Age, and Physical Stats

Julio Diaz stands at 174 cm, which is about 5 feet 9 inches tall. He weighs approximately 70 kg, or around 154 pounds. He turned 21 in January 2026. For a left back, his build is fairly standard. He is not the tallest defender out there, but he makes up for it with pace, agility, and good positioning.

His preferred foot is his left, which is natural for a left back. One of his strengths is his ability to play as both a left back and a left winger, giving coaches tactical flexibility. That versatility has been highlighted by both Atletico Madrid and scouting reports as one of his most valuable attributes.

International Career

Julio Diaz has represented Spain at multiple youth levels. He started with the Spain U18 team in 2022, then moved up to the U19 squad where he earned around 10 to 12 caps between 2023 and 2024. He was selected for the Spain U20 team in 2025 and earned 7 caps at that level.

A notable highlight was his selection as the starting left back for Spain at the U20 World Cup held in Chile in 2025. Playing in a global tournament at that age is a strong indicator of his standing within the Spanish football setup. Across all youth levels, Icon Polls research shows he has accumulated approximately 30 international appearances, a solid number for a player his age.
