Athletic Bilbao defender Fernando Amorebieta is on the radar of Barcelona.
Barca coach Pep Guardiola has concerns over his central defensive options with both Carles Puyol and Gerard Pique struggling with their fitness this season.
Spain international Amorebieta has emerged as a potential target for Guardiola, who has discussed the 26 year-old with sports chief Andoni Zubizarreta.
The centre-half is tied to Bilbao until 2013.
