Farre says the Dutchman would remain in charge should he win the January election.
He said, "He is a Barça legend. When we win I will talk to him and tell him about our sports director, who will be able to be announced to you in a few days, because he is leaving a club.
"We will talk to him and find out what he wants to do, if he likes the project he will continue because he is a legend but I don't know if he wants to continue. He entered with a project and I know that he is already fed up.
"I hope he renews the day after my election."
