Xavi, renowned for controlling play from a central position, said his ability to recover after a game was declining.
"I've had luck not to be injured and I think my career has come towards its end, there's been a descent," he told Spanish newspaper Sport.
"Qatar allowed me this. Now I see myself being more tired, it's harder to recover, it will surely be my last year of being a footballer.
"I have the idea of getting my coaching licence next year and being a coach."
Xavi collected 133 caps for Spain during a 14-year international career, winning the 2010 World Cup and the European Championship in 2008 and 2012.
