The Argentine stopper, who played for the Gunners in their 2020 FA Cup final victory, has left for first-team football at Villa Park
Emi Martinez has left Arsenal after his £20 million ($25m) transfer to Aston Villa was confirmed on Wednesday.
However manager Mikel Arteta has chosen Bernd Leno as his No 1 for the coming season, leading Martinez to end his long asssociation with Arsenal and seek first-team action elsewhere.
The 28-year-old moved to Arsenal more than 10 years ago, in August 2010, from home town club Independiente. Often a back-up who was regularly sent out on loan, Martinez moved into the spotlight at the end of the 2019-20 season after Leno suffered a shoulder injury in the Premier League defeat to Brighton.
Martinez started the final 11 games of Arsenal’s campaign as the English football season resumed following coronavirus-enforced shutdown. He also played all six of Arsenal’s games in the FA Cup last season, conceding just three goals.
The Gunners lifted the FA Cup at Wembley as they beat Chelsea 2-1, and Martinez also got his hands on silverware in his final competitive Gunners match as they beat Liverpool in the Community Shield.
