The Spain international has long been linked with a return to Barcelona, who he left to join Arsenal as a 15-year-old.
He said when asked is he could be at Arsenal for his whole career: “Why not?
“I have never really thought about it, staying here all my life, because I am only 22 and you never know what your career will bring – but why not?
“It is my seventh season now, I am really happy, better than ever, so you never know.”
