In the end, Brazil crashed out of the World Cup at the quarter-final stage to Croatia on penalties, despite being the favourites going into the finals.
Shockingly, the 25-year-old has actually never been capped at senior level for Brazil despite first appearing for the U20s back in 2017.
He was named in the squad for the 2020 Summer Olympics but was forced to pull out through injury as his country went onto win gold in Tokyo.
‘I was definitely sad. It’s normal for an athlete, even more so for having been in the group and then missing the last call-up,’ Gabriel told ESPN Brasil.
‘I had my family close by, and at Arsenal everyone talked to me. I have a strong mind and I’m a family person. I managed to digest that well, it’s part of football.
‘I’ll keep working and I know there are other World Cups ahead of me. I’ll work to be there.’
Gabriel has been very impressive for Arsenal since joining Mikel Arteta’s side from Lille in 2020 for £27million.
His efforts this year have helped the Gunners go five points clear at the top of the table after 17 games and he puts his performances down to how well adapted to the Premier League he now is.
The defender added: ‘Arriving at a club like Arsenal makes all the difference and I’m very happy to be here. Playing in such a difficult league and one of the best in the world.
‘Since I arrived, I’ve learned a lot and certainly at the beginning it was difficult, but now it’s better. I’m well adapted. I understand more about the Premier League and how Arsenal play.
‘That made it easier for me. The biggest difficulty I faced was the style of play, but I work a lot on a daily basis. I believe that I have improved since I arrived. I am very happy to learn more and more.’
