Barcelona sporting director Andoni Zubizarreta insists they can handle the absence of Lionel Messi.
Messi is out for three weeks with a thigh injury and won't make their Champions League clash with Celtic.
"He's a very difficult player to replace," Zubizarreta told reporters as Barca prepared to fly to Scotland.
"We must do without the best player in the world, but we have a squad with extraordinary players.
"The players who are here are very good and we have to play with what we have."
