The Mirror says the Spanish giants were already on the lookout for a new No.1 with Victor Valdes on his way out of the Nou Camp this summer.
But back-up stopper Jose Pinto's decision to follow Valdes' lead by rejecting a new deal means Barca are now on the lookout for two top-class goalkeepers.
Juventus are eyeing Krul, and now Barca have joined them in looking at the Dutch keeper.
The Catalan club remain confident that their transfer ban - imposed because they had breached rules on the transfers of players aged under 18 - will at the very least be put on hold while an appeal is made.
