Newcastle United are reportedly interested in signing 19-year-old Real Madrid defender Diego Aguado, who is also of interest to multiple clubs across Europe. The Premier League club hopes to sign him in the summer. Newcastle are said to be seeking more quality and depth for their defense, and the versatile player, who can operate as a central defender or a fullback, would be viewed as a signing for the future. Real Madrid may not be able to provide the young player with regular opportunities, and a move could be suitable for his development.
