Xavi can see Bayern Munich coach Pep Guardiola eventually returning to Barcelona.
Guardiola has been linked with a 2016 move to Manchester City this week.
Al Sadd signing Xavi says: "I enjoyed a successful period at the club with Pep and he will choose the right time to return to Barca."
Xavi also revealed he has plans for a football career once he hangs up the boots.
"Football is my life and will not walk away. I hope to become a sporting director or coach."
