Diego Leon is a Paraguayan professional footballer who currently plays as a left-back for Premier League club Manchester United and the Paraguay national team. Born on April 3, 2007, Leon gained international prominence following his $9.5 million (£4 million) transfer from Cerro Porteño to Manchester United in July 2025. As of March 2026, he is a regular fixture in United’s Under-21 squad, where he has recorded over 800 minutes in the Premier League 2, while remaining a key prospect for Paraguay’s 2026 FIFA World Cup squad.
Early Life and Cerro Porteño
Diego Basilio León Blanco was born into a large family in Colonia Yguazú, Paraguay, as the youngest of nine siblings. His early years were defined by modest means, where he famously fashioned makeshift footballs from bundles of clothing to practice his craft.
His professional breakthrough came at Cerro Porteño, one of Paraguay’s most prestigious clubs. He made his senior debut in August 2024, scoring the winning goal in a 1-0 victory over Sportivo Ameliano. Before his 18th birthday, Leon had already amassed 33 senior appearances and four goals, earning the title of the 4th best Under-18 footballer in the world according to CIES rankings in 2024.
Manchester United Transfer (July 2025)
Manchester United officially confirmed the signing of Diego Leon on July 5, 2025, following a deal negotiated during the previous winter window. The transfer fee was approximately £4 million ($9.5 million), signaling United’s commitment to the INEOS-led vision of recruiting elite global youth talent.
Upon his arrival, Leon became the first Paraguayan player to sign for Manchester United at the senior level. While initially integrated into the Academy and Under-21 setups to adapt to the physicality of English football, he was immediately handed the number 35 shirt and began training frequently with the first-team squad under manager Rúben Amorim.
2025/2026 Season Statistics
During the 2025/26 campaign, Leon has been a standout performer in the Premier League 2. As of late March 2026, he has accumulated significant match experience, demonstrating the offensive instincts that saw him transition from a winger to a modern attacking full-back.

His first goal in a United shirt came in October 2025 during a 4-1 victory over Tottenham’s Under-21s. His performances have been characterized by a high volume of successful dribbles and defensive recoveries, ranking him among the top-performing left-backs in the development league.
International Career and World Cup
Diego Leon’s international trajectory has been equally steep. After representing Paraguay at the Under-20 South American Championship in early 2025, he earned his senior debut for the Paraguay national team on October 14, 2025.
Heading into the summer of 2026, Leon is a primary candidate for Paraguay’s World Cup roster. The Albirroja are set to face the United States and Australia in Group D. Despite concerns from the Paraguayan press regarding his lack of Premier League first-team minutes, his agent and national team coaches remain confident in his readiness for the global stage.
