The England attacker was the subject of a lengthy contract saga earlier in the season, but to the relief of fans confirmed that he penned a new deal with the Gunners with the aim of bringing silverware to the club.
The 24-year-old told The Times: "People now can surely see it didn't revolve entirely around money. I could have hung on and walked out for nothing and who knows what I could have made then? My agent might know, but he never told me and I never asked. I just wanted to be in the team, playing well.
"I always said I wanted to stay. I know what I owed to Arsenal and to the manager, getting me when I was 16. I did want to re-pay the club. Others might say that and not believe it, but I do.
"When a club and a manager have shown interest in you at such a young age, when you've done next to nothing in the game, and they've helped you reach the top level, helped you develop and work around top players, you don't lightly walk away from that.
"I wanted to stay because I still think this club can go on to achieve something. It's 'when' and not 'if' we win something.
"If anything came out of it all, I think it's a bit more respect between me and the manager. We've shown faith in each other and I feel there is a bit more responsibility on me to create something out of nothing."
