"I am lucky that the two clubs have asked about me and that's very important - that does not happen every day."
The Gunners' skipper also spoke of his sadness at not being able to join his boyhood club Barcelona, but insisted he is happy at Arsenal and just wants to win trophies with the club.
"We tried for the summer but in the end could not be. In my head I thought it might have happened. It was a very good opportunity for me but here [at Arsenal] I have everything, just need to win titles," he said.
"I was always very happy when I was in the Barca youth ranks and when I went it is clear that saddened me.
"In the future I do not know what will happen. Playing in Barcelona is a dream I've had since I was very young."
