The Spain international thinks it will be hard to stay at Camp Nou until his career comes to an end and says he has not decided if he will take up coaching in the future
The midfielder, who turns 34 later this month, has a contract with the Catalans until the summer of 2016 and has already made 22 appearances this season.
Though he insists he would like to stay at Barca until the end of his playing days, Xavi thinks that it will be tough to remain in the Liga champions' first-team plans as his illustrious career draws to a close.
"It's difficult to finish your career here," the Spain veteran told Panenka Magazine. "I don't know if I will end it at Barca. I'd like to, but I don't know what will happen.
"I feel good physically, better even than in the last two seasons. I don't want to miss any games and sometimes that can affect you. I have to give myself a little bit more rest now.
"I am happy playing for Barca because of our philosophy. Perhaps I could have been happy playing for another club, I don't know, but my priority has always been Barca."
Xavi also spoke about the possibility of becoming a coach and, though he refused to commit himself to the idea of taking charge of a club in future, he laughed off the notion that he would exit the world of football upon hanging up his boots.
"I don't know if I will be a coach because I am still playing and I haven't stopped to think about it yet," he added. "But I like football a lot and I will stay linked to it. What on earth would I do otherwise - become an economist?"
