According to Biography, Dortmund is interested in Real Madrid's 18-year-old defender Diego Aguado, but has not yet made a formal offer.

Aguado is a Spanish local player and was selected for the Spanish U20 team. He is 1.84 meters tall and can play as a center back or left back. Aguado has only played once in the Copa REE for Real Madrid's first team.

Aguado's current valuation in the transfer market is EUR 1 million, but Real Madrid's asking price for him has reached EUR 10 million. Dortmund thinks this is too high. On the other hand, the position Aguado plays is not a priority for Dortmund's signings this summer. Dortmund now hopes to give priority to introducing an offensive player (this player is better competent for two positions, one is the winger and the other is the midfield position behind the striker).
