Martinez is being linked with Barca as a replacement for departing captain Carles Puyol.
"These are all rumors, assumptions, speculations. If six names are on the list, they are all rumors. I have not heard that Andoni Zubizarreta (sporting director of FC Barcelona) has spoken publicly about one of those named," Inaki Ibanez told fussballtransfers.com.
"His only target is to fight for a place in Spain's World Cup squad."
