Gabriel has insisted that his English is good enough, despite his manager's claims to the contrary.
The Gunners boss suggested after the 3-2 defeat to Manchester United last month that the Brazilian's lack of verbal skills had contributed to a poor defensive performance from his side as the centre-back had not been able to communicate well with his fellow defenders.
However, Gabriel insisted that he has no trouble understanding his teammates and stressed that his English skills, along with his performances on the pitch, are already improving.
He told IBT: "I already understand my teammates on the pitch. I still miss some things but I am improving.
"I'm already 100% recovered from my last injury and now I just have to keep working to improve further. I still have a long way [to feel like a starter]. I'm working very hard but the competition is high because my teammates are at the top level.
"I am training very hard and trying to take every opportunity in the games and I think I'm doing things right."
The 25-year-old defender moved to the Emirates Stadium from Villarreal in January 2015, but has failed to nail down a regular place in Wenger's side since his arrival.
After playing just eight times in the second half of last season, the defender has featured in only 14 Premier League matches for the club this season, due mainly to failing to break up the partnership of Laurent Koscielny and Per Mertesacker.
He may well continue in action in the next few weeks, however, with Koscielny set for more time on the sidelines.
