The Brazil international has stated that he has adapted to his new environment and is hoping to improve.
The Brazil international joined the North London club from Villarreal in the January window to bolster Arsene Wenger’s options at the heart of the team’s defence.
The South American enforcer had a few injuries upon his arrival at the Emirates Stadium but looked solid in the games he did play - he started four Premier League games last term.
With Gabriel set to fight it out with Laurent Koscielny and Per Mertesacker for a first-team berth next season, the former La Liga star has admitted that he has adapted to life in England.
“I’ve only been here for a short while but I think it is a wonderful experience,” he told the club’s official website.
“I am learning a lot with all my colleagues, with the city and with this club, which I have no words to describe because it is so great. I am very happy.
“I think it involves everything; the family helping outside and the team-mates helping within the club. I think this combination helps my happiness grow more every day.
“When I first arrived it was my time to adapt. I think I am more adapted now, so I really want to win, I want to be at my best to be able to do all I can to help everyone.
“I do think that my characteristics of being strong have helped me adapt well to the English league because it is a very hard league, with a lot of contact.
“So I have been making the most of it to get better all the time.”
Arsenal are in Singapore in pre-season and will hope to hit the ground running when they return for the start of the new Premier League campaign next month.
The Gunners’ defence has been bolstered by the acquisition of Petr Cech from Chelesa, with a stringent back line key to the North London outfit putting forward a sustained title challenge in 2015-16.
