Arsenal have signed Iceland goalkeeper Runar Alex Runarsson on a four-year deal from French club Dijon.

The 25-year-old joins the Premier League side as cover for Bernd Leno, following the departure of Emiliano Martinez to Aston Villa.

Runarsson joined Ligue 1 club Dijon in July 2018 and made 13 appearances last season.

"I'm just extremely happy and proud, it is a big day for me and my family," he said.

"I know it is going to be a lot of hard work, but I am ready to do everything I can to get the most amount of minutes as possible."

Arsenal manager Mikel Arteta said: "We want to create healthy competition for places and we look forward to seeing Alex bring further depth to the goalkeeping position."
