It's been suggested the Germany attacker is ready to quit in the summer.
He told arsenal.com: "I enjoy it here. The supporters in England are very good - the Arsenal fans of course, but the others too. Everywhere I go they’re happy, funny and friendly. I feel very good here, both in the stadium and out of it.
"At away matches, I see our away support, three or four thousand people, and the atmosphere they make - I feel proud of them, and of the Club.
"It is important to talk to them and I like writing a few things on Twitter, taking photos, things like that. I have fun and hopefully people enjoy it."
