Xavi said he "really wants to go home", with Barcelona in talks with Al Sadd to make him their new head coach.
Barca's first vice-president Rafael Yuste and director of football Mateu Alemany were in attendance for Al Sadd's 3-3 draw with Al Duhail on Wednesday, a result that kept Xavi's side three points clear at the top of the Stars League.
The former midfielder, who made 767 appearances for Barca as a player and won 25 trophies during an illustrious spell for the club, has been the frontrunner to take over following the dismissal of Ronald Koeman last week.
Al Sadd last week insisted Xavi was solely focused on the Qatari club, with whom he has a two-year contract, but the coach confirmed an agreement on his future could be reached in a matter of hours.
"I really want to go home. The two clubs are in talks and a resolution must be reached. I am very excited, but it's a matter of respect – I have a contract," Xavi told Mundo Deportivo.
"It would be a return home. The two clubs have to agree. Hopefully it will be done, because I am very eager and excited.
"I am very positive. I have been very clear about my position. I think it will be a matter of hours, maybe days. They know my stance and hopefully it can be done."
He added to TV3: "I am a positive person and it is a matter of common sense. They have to agree. The two clubs know my position and I hope it will be sorted soon."
After a 1-1 draw with Deportivo Alaves in their first game since Koeman's dismissal, Barca boosted their qualification hopes in the Champions League by beating Dynamo Kiev on Tuesday.
Speaking more generally about what Koeman's successor needs to do at Camp Nou, Xavi added: "The coach who goes does not have to be a messiah. We saw a different Barca yesterday.
"Everyone has to row in the same direction for Barca to win games. We are all very excited. We will see if it ends up being done, but it would be spectacular."
