Athletic Bilbao coach Marcelo Bielsa is interesting Barcelona.
AS says Barca chiefs have drawn up a contingency plan in the event Pep Guardiola decides to move on in the summer.
High on their shortlist of candidates is Argentine Bielsa, who also enjoys the endorsement of Lionel Messi.
"He is a coach I would like to play for," said Messi. "I admire what he did with Argentina, Chile and what he is doing with Athletic."
