Borussia Dortmund is reportedly interested in Milton Delgado, a 20-year-old defensive midfielder from Boca Juniors. Eintracht Frankfurt has also become an interested Bundesliga club, and Bayer Leverkusen has reportedly been on that list for some time. Although the Argentine U20 international has a contract until 2029, Boca Juniors is said to be willing to allow his transfer to a European club. The Argentine club would likely accept a transfer fee between ten and twelve million euros. Delgado joined Boca Juniors in January 2024 and has 20 caps and one goal for Argentina's U20 team. He has made 15 appearances and provided one assist in the 2025/2026 domestic league season.
