The Germany ace - an £11million capture from Cologne last summer - has rubbished the wayward reports.
He said: "Overall I am happy. I believe I have the quality to play in every game here and think I have done well until now.
"I've scored some goals and made some assists, so I am content. The supporters in England are very good.
"Everywhere I go they are happy, funny and friendly. The Arsenal fans make me very proud."
