The France Under-21 international was rewarded with a new long-term contract at Emirates Stadium at the start of the year.
But he told L'Equipe: "In July, I met the coach and he told me I am a full member of the team and he relies on me. Looking at who we have signed, they have trust in me.
"Alex Song left for Barcelona and they didn't (sign) another defensive midfielder.
"When I didn't play in the first three matches it made me think about it. But I know I will get an opportunity and I will seize it.
"Arteta, Diaby and Cazorla are great players, who have more experience than me. But during training sessions every morning I am not behind them.
"I am 21-years-old, I know I cannot be patient any more. This year is the right season to make a name for myself at Arsenal.
"I have given myself six months and then I will take stock. If I see it is blocked, I will go somewhere else. But for now I know I have the qualities to make a name for myself at Arsenal."
