The World Cup winner is believed to be one of several candidates to replace under-fire Ronald Koeman, who is not expected to remain in charge of Barcelona for the long term.
Xavi is currently enjoying a successful stint with Qatari side Al-Sadd, but he has refused to rule out the possibility of taking the reins at La Blaugrana after initially rejecting an approach from his former club.
Speaking to reporters, Xavi said: "Yes, I feel ready to coach any team in the world. When they offered me it, I'd only been a coach for three months, but now it's different.
"I have more experience and I'm learning a lot here. I want to tell everyone that I'm very happy in Qatar and my idea is to keep achieving success with this team."
Xavi oversaw Al-Sadd's Qatari Cup victory over Al Rayyan on Friday, and the 41-year-old previously posted 85 goals and 185 assists from 767 games in a Barcelona shirt. body check tags ::
