The former Barca midfielder’s contract with Arsenal expires in 2014, but it is expected the 19-year-old would be keen on a return to Spain before that.
Fabregas said: “It is obvious that I am very happy at Arsenal, but I cannot predict what will happen in the future.
“My girlfriend is Catalan and I expect that I will finish my career playing back in Catalunya.”
He added: “I do not know where I am going to be in two, three or four years.
“I am 19. I am only young and I have much more to learn.”
