Karl Hein, a prodigious talent of the Gunners academy has extended his stay at the club after signing a new long-term contract. The 19-year-old is yet to start for the first team.
The Estonian goalkeeper hasn’t yet touched 20 but already has 10 senior international caps with his country.
He was inducted in Arsenal’s Europa League matchday squads last year, six times. He might just make his senior club appearance this season.
