The centre-half has been added to Dunga’s contingent to face Chile and France, with an international debut on the cards.
The 24-year-old centre-half will replace the injured David Luiz, who has had to withdraw from Dunga’s contingent.
The Gunners signed the Sao Paulo born enforcer from Villarreal in January, and although he has been on the sidelines of late with a hamstring strain, has looked impressive at the back for Arsene Wenger’s men.
Gabriel has started two Premier League games so far and featured in another from the bench, providing the North London club with extra competition for places at the heart of their rearguard.
The Arsenal man is in line to make a potential international debut for the South American nation, with friendly fixtures against Chile and France coming up before the end of the month.
Gabriel did not represent his country at age-grade level and as such will be keen to make his Selecao bow.
With the Copa America set to take place this summer, the Gunners defender will hope to make an impression.
Brazil’s clash with Chile will be played at the Emirates Stadium and as such Gabriel could well have the chance to make his international debut in front of the Arsenal faithful.
