Sevilla have secured a major boost to their squad with the signing of Julio Díaz, who joins the Spanish club after both parties reached an agreement for the transfer of 50% of his rights for a fee of around 1.5 million. The left-back, who last season made his debut under Simeone and went on to play four games, becomes Sevilla's first signing for the upcoming season. The signing of Julio Díaz is a big step for Sevilla, who are looking to improve their position in the La Liga table, where they currently sit 16th with 34 points, 9 wins, 7 draws and 15 losses in 31 games, and with a goal difference of -12. Julio Díaz will join the Sevilla squad that travels to the Netherlands on Thursday for a training camp. The left-back did not participate in Atlético Madrid's training session and is expected to sign his contract with Sevilla in the coming days.
