The Germany international has settled into life in north London well, scoring three goals in his first five games for Arsene Wenger’s men.
The forward has a tattoo of form club Cologne and is considering a Gunners’ crest to rival it.
“Maybe on this one – my left arm – in a few years,” he revealed to Mirror Football.
“Cologne meant so much to me because I was there a long time. Maybe I will do the same with Arsenal because I like this club.
“It is a big club and maybe we can do a tattoo. We can speak about this in the next three or four years.
“When I came on the first day to the club everyone made it easy for me. Not only the team around the team, the coaches, the physios, the president and all the staff make it easy for me. I feel happy at Arsenal. It is good for me.
“The team and Arsene Wenger make it easy on the pitch. Last week we played very well. This is the style of football that I like – we play with one or two touches.
“We play straight to the front and this is the style that I like. But we have only played four or five matches and we are not ready to speak about the title or the Champions League.
“We must carry on playing like the last few matches and we must keep on fighting.
“When you are playing up front you want to score goals and like to score goals. when you score goals you are very happy for yourself and for the team.
“I don’t know about targets – we will see. We have only played four or five matches and I have three goals and I am very happy about the good start for me and for the team.
“We must keep fit and well – it is a long, long season and we don’t have a break in the winter like in Germany. So it is different for me, but I like to play football and be on the pitch,” he concluded.
