Barcelona chief Robert Fernandez admits president Josep Maria Bartomeu will choose the next coach.
Luis Enrique will walk away from Barca at the end of this season.
Asked about the prospect of Lucho's No2, Juan Unzue, being promoted, Robert was coy.
"Well, I hear a lot of things but when the season is over, we will decide with the president who will be the coach," he said.
Robert added: "I hope everyone returns well from the national team because we need all the players to face the final straight. It won't be easy but I'm convinced that there will be a fight to the end."
