Goalkeeper Alex Runarsson has signed for Arsenal on a four-year contract from French club Dijon.
The 25-year-old Iceland international joined the Ligue 1 club in July 2018 and made 13 appearances for them in all competitions last term.
He started his career with KR Reykjavik in his home country. He went on to join FC Nordsjaelland in Denmark, where he made 62 appearances during a three-year spell, before moving to Dijon.
Mikel Arteta added: “We want to create healthy competition for places and we look forward to seeing Alex bring further depth to the goalkeeping position.”
The played is expected to be Arteta's No2 choice behind Bernd Leno following the departure of EMi Martinez to Aston Villa last week.
