Barcelona are weighing up a shock move for Zenit St Petersburg veteran Branislav Ivanovic.
Hit by a fresh injury setback for Thomas Vermaelen and fitness concerns continuing over Samuel Umtiti, Barca are expected to seek a new defensive signing in January.
Mundo Deportivo says on Barca's shortlist is former Chelsea defender Ivanovic, now 34.
The Serb has been outstanding for Zenit so far this season, playing every minute of their ten games so far.
Barca would hope to do business for a cut-price fee should they firm up their interest in Ivanovic.
