Is it? I've not seen anywhere that it was without consent of Udinese. Furthermore, the Pozzi's ownership model is to loan out and sell players for profit. I've seen nothing to suggest Zielinski was being developed to be used by his current club while out on loan for the last two seasons. Had Udinese stated that he wasnt for sale, then it might be a case of tapping up. But even then most transfers happen that way, and if it is to a player that was going to be sold anyway, i cant see it being a problem.
