Chelsea are close to finalizing the signing of goalkeeper Emiliano Martinez from Aston Villa, with the 33-year-old set to undergo a medical in London. The move follows growing concerns over current goalkeeper Robert Sanchez, who has been linked with a potential exit. Martinez, a key player for Argentina, is expected to join the Blues in a deal valued at £7.5 million. Villa, who recently signed forward Zion Suzuki from Parma for £30 million, have agreed to release Martinez after he opted to leave the club. The transfer marks a significant shift for Chelsea as they look to strengthen their defensive options ahead of the new season. Martinez’s return to London, where he began his career at Arsenal, adds a familiar element to his new team. The deal is seen as a strategic move to address long-term goalkeeping challenges, with manager Xabi Alonso hopeful the signing will provide stability in goal.
