We are delighted to confirm Karl Hein has signed a new contract with the club.
The Estonia international joined us in 2018 from his hometown club, Nõmme United, where he made his debut at the age of 16.
Karl began his Arsenal career as a scholar and turned professional the following year. During the 2020/21 campaign, he featured in our first-team squad for the first time in a Europa League game.
He spent the second half of the 2021/22 season on loan at Championship side Reading, making five league appearances for the Royals, and went on to make his full Arsenal debut in a Carabao Cup game against Brighton the following November.
