Chelsea secures veteran Argentine goalkeeper in £7.5m deal

Chelsea have completed the signing of 33-year-old goalkeeper Emiliano Martinez from Aston Villa for £7.5 million. The Argentina international, who made 256 appearances for Villa, has agreed to a two-year contract with an option for a third season. His move follows a breakdown in a proposed transfer to Juventus and comes after Chelsea's starting keeper made errors in their season opener.
