Teenage goalkeeper Joao Virginia has signed his first professional contract with Arsenal.
Virginia, who turned 17 on Monday, has played for the Gunners in the Uefa Youth League and is a member of the club’s Under-18s squad.
He was part of Portugal’s squad for the Olympics in Rio this summer and has represented his country at youth level.
The ex-Benfica youngster helped Arsenal to victory in the Under-17 ABN AMRO Future Cup last season, making three penalty saves in the final against Anderlecht.
