"I am aware it's a great club and I have a four-year contract. I know there's talk about me and Barcelona and Bayern, but people make their own conclusions," he told reporters at a press conference.
"The facts are simple: I have a contract at a club where I am happy. Full stop. We all know how situations change in football but I repeat that I'm not one to make castles in the sky. I live in the moment, I seek nothing but to play the best I can.
"In my mind my goal is to win trophies with Arsenal with whom I'm about to start pre-season training. I've no ulterior motives. I'm at a healthy club, which plays beautiful football, doesn't lose money every year, sticks to its own budget and plays in the Champions League. Not many players can say the same."
Koscielny joined Arsenal from Lorient in 2010.
