Barcelona are eyeing Ajax defender Lisandro Martínez for the January market.
Barca are seeking a new centre-half signing for next month's transfer window as senior defender Gerard Pique recovers from a knee injury.
Manchester City youngster Eric Garcia is Barca's top choice, though Argentine Lisandro is also being discussed.
Ajax would be willing to sell for around €20m - meaning Barca will have to sell first to fund any bid for the stopper.
Instead, the Catalans wish to negotiate a six month loan with the option to buy in June.
