Valladolid showed interest in signing Dominik Prpić this summer. They proposed a swap deal involving Biuk for Prpić, but Hajduk Split rejected the offer.

A proposed swap deal from Spain suggested loaning Stipe Biuk to Hajduk Split in exchange for selling defender Dominik Prpić to Real Valladolid. However, this story also seems unlikely as Hajduk Split does not want to part with their talented defender at this time.
