It's emerged Barca are now willing to pay the defender's €30m buyout clause with Sevilla showing an unwillingness to discuss terms.
Caparros snapped: "It seems that they have paid his clause although they have not told us anything since the end of the season. It is something that we feel a lot.
"We are going to try to sign three or four more players who are already in advanced negotiations. Let's see if after the World Cup there is more tranquility."
On the possibility of Barca fullback Aleix Vidal arriving, he added: "He is a footballer who is there, but his price is high. We are well covered in that position."
