Gabriel slotted seamlessly into the Gunners defence during his first season in London, impressing with his combativeness and composure in the back line, and contributing some important goals too.
In fact he netted on his debut, away to Fulham on the opening day of the season, and was named Arsenal.com Player of the Month for September, October and November - reward for an explosive start to his career.
The Brazil youth international is a cultured, imposing left-footed defender who is also comfortable playing the ball out from the back. Before joining Arsenal from Lille, Gabriel (full name Gabriel dos Santos Magalhaes) had started his career with Avai in Santa Catarina, Brazil.
He played for his country at the 2017 South American U-20 Championships, and was part of the Under-23 squad at the summer Olympics in Tokyo.
