Barcelona president Josep Maria Bartomeu says the club are on the lookout for a centre-back, although they could also look to the B team to strengthen their defence.
Injuries to Thomas Vermaelen and Samuel Umtiti have left Barcelona short at the back with Clement Lenglet and Gerard Pique their only fit senior centre-backs.
The club have already been linked with a host of defenders ahead of the January transfer window including Toby Alderweireld, Branislav Ivanovic, Matthijs de Ligt and Dejan Lovren.
Meanwhile, there have also been reports Ernesto Valverde could call up Jorge Cuenca or Chumi from the B team.
