Early Life and Football Background
Diego Manuel Jadon da Silva Moreira was born on August 6, 2004, in Liège, Belgium. Coming from a footballing family, he grew up surrounded by the sport. His father, Almami Moreira, was a professional footballer who represented Guinea-Bissau internationally and played for several European clubs, including Standard Liège.
Diego began his football development at Standard Liège, the Belgian club where his father had also played. His technical ability and attacking potential quickly attracted attention, and in August 2020 he moved to Portugal to join Benfica’s academy.
The move proved decisive for his development. At Benfica, Moreira received high-level coaching and gained experience in a competitive youth system known for producing talented professional players. Primarily a left-footed winger, he became recognised for his acceleration, dribbling ability and confidence when facing defenders.
Benfica: A Breakthrough in European Youth Football
Moreira’s rise at Benfica was particularly impressive during the 2021–22 season. He became an important member of the club’s Under-19 team, helping Benfica win the UEFA Youth League for the first time in their history.
His performances in the knockout stages were especially memorable. Moreira scored twice and provided two assists in a 4–0 quarter-final victory over Sporting CP. He also contributed two assists in the final, where Benfica defeated Red Bull Salzburg 6–0.
The achievement established him as one of the promising young attacking players in European football. He also helped Benfica win the FIFA U-20 Intercontinental Cup in 2022, adding another international youth honour to his growing record.
Moreira subsequently progressed into Benfica B and made his senior debut for the first team on May 13, 2022, in a Portuguese league match against Paços de Ferreira. He also appeared in a Champions League qualifying match against Midtjylland later that year.
Despite his progress, his relationship with Benfica became complicated by contractual discussions. After his contract expired in 2023, he left Portugal in search of a new opportunity.
Chelsea: A Move to the Premier League
In July 2023, Moreira joined Chelsea as a free transfer after leaving Benfica. The move offered him the chance to experience English football and develop within one of the Premier League’s most ambitious clubs.
He made his Chelsea first-team debut on August 30, 2023, starting in an EFL Cup match against AFC Wimbledon. However, competition for attacking positions made it difficult for him to secure regular opportunities.
Chelsea therefore arranged a loan move to Olympique Lyonnais in September 2023, allowing the young winger to gain experience in Ligue 1.
Lyon: A Challenging Loan Spell
Moreira’s time at Lyon did not develop as expected. He made nine first-team appearances across Ligue 1 and the Coupe de France but struggled to establish himself as a regular member of the starting eleven.
The club was experiencing significant instability, and the pressure to deliver results made it difficult for a young player to earn consistent opportunities.
Chelsea recalled him in January 2024. Although the loan spell was relatively short, it provided valuable experience of senior football in France and helped prepare him for his next move.
Strasbourg: Establishing Himself in Ligue 1
On August 16, 2024, Moreira completed a permanent transfer from Chelsea to RC Strasbourg. The move gave him an opportunity to settle at a club where young players could play an important role in the first team.
He quickly became an influential member of Strasbourg’s squad. His pace and technical ability offered the team a direct attacking option, while his versatility allowed him to operate in different positions on the left side of the pitch.
Moreira scored his first goal for Strasbourg in a 1–0 victory over Marseille on September 29, 2024. As the season progressed, he became increasingly important to the team’s attacking structure.
During the 2024–25 Ligue 1 campaign, he made 32 appearances, scoring twice and providing seven assists. His performances earned praise for his ability to create chances, carry the ball forward and contribute consistently to the team’s attacking play.
He continued to improve in 2025–26, recording four goals and six assists in 27 Ligue 1 appearances. Across his two seasons at Strasbourg, he developed into a versatile and productive player, attracting attention from clubs across Europe.
AC Milan: The Next Step in His Career
In August 2026, Moreira joined AC Milan in a major transfer reportedly worth around €50 million. The deal represented a significant financial achievement for Strasbourg and one of the most important moves of Moreira’s young career.
Milan offered him an opportunity to compete in Serie A and continue his development at a club with a rich European history. His versatility was an attractive quality for the Italian side, particularly given his ability to operate as a winger or in a more advanced wide-midfield role.
He made an immediate impression. In a September match against Lazio, Moreira scored twice after coming on as a substitute, helping Milan recover from a two-goal deficit to draw 2–2.
His early performances suggested that he could become an important attacking option for the Rossoneri. Having already experienced Portuguese, English and French football, he arrived in Italy with a level of senior experience uncommon for a player of his age.
Playing Style and Strengths
Diego Moreira is primarily a left-footed winger who can operate on either flank. He is also capable of playing as a left midfielder or left wing-back, making him a tactically flexible option.
His most noticeable strength is his ability to beat opponents in one-on-one situations. With quick acceleration, close ball control and confident dribbling, he can create space in wide areas and carry the ball into dangerous attacking positions.
Moreira is also comfortable receiving possession under pressure and driving forward. Rather than relying exclusively on crosses, he can move inside, combine with teammates and create opportunities through short passing sequences.
His development at Strasbourg added another dimension to his game. He became more disciplined in defensive transitions and demonstrated an ability to contribute beyond the final third.
Nevertheless, improving his consistency remains important. To become a regular starter at a club like AC Milan, he will need to maintain his attacking productivity while continuing to develop his defensive awareness and decision-making.
International Career with Belgium
Moreira initially represented Portugal at several youth levels, progressing through the Under-16, Under-18, Under-19, Under-20 and Under-21 teams. His performances included participation in the 2023 UEFA European Under-21 Championship.
Although born in Belgium, he had chosen to represent Portugal during his youth career. However, in May 2025, FIFA approved his request to switch international allegiance to Belgium.
He subsequently received his first senior call-up to the Belgian national team in 2025 and made his debut during the country’s World Cup qualifying campaign. The decision gave him the opportunity to represent the country where he was born at senior international level.

His international career remains an important part of his development, with competition for places in Belgium’s attacking positions providing another challenge.
Future Prospects
At 22, Moreira has already experienced several major European football environments. His journey from Standard Liège to Benfica, Chelsea, Lyon, Strasbourg and AC Milan demonstrates both his ambition and his ability to adapt to different playing styles.
The move to Milan represents a significant test. Serie A demands tactical discipline and intelligent positioning, particularly for wide players who must contribute in both attacking and defensive phases.
If he continues to develop his decision-making and maintain the direct attacking qualities that made him successful in France, Moreira has the potential to become an important player for Milan and Belgium.
Conclusion
Diego Moreira’s career is a story of steady development, international experience and ambitious moves between major European clubs. From winning the UEFA Youth League with Benfica to becoming an influential player at Strasbourg, he has consistently demonstrated his attacking potential.
His transfer to AC Milan in 2026 marks a new chapter and offers him the opportunity to establish himself at one of Europe’s most prestigious clubs. With his pace, dribbling skills and versatility, Moreira is a young talent worth following. For football fans keeping up with emerging stars through Xoilac, his performances in Serie A and for Belgium will be particularly interesting to watch.
