Xavi has signed a new deal with Al Sadd to 2021.
However, Sport says a clause has been included that would allow him to leave at any moment.
The former Barcelona midfielder has agreed on a new deal to coach the Qatari side until June 2021, timing with presidential elections. He has never hidden his desire to coach in the Camp Nou dugout.
With the release clause in his deal, Xavi would be able to rescind his contract and accelerate a move to Barça if he decided he wanted to.
Barca president Josep Maria Bartomeu tried to appoint him in January as Ernesto Valverde's replacement but Xavi declined the offer as the moment was not right.
If Quique Setien doesn't remain in charge, Bartomeu could move for Xavi again, although Xavi would need significant promises to consider the job in the short-term.
