Valencia striker Nikola Zigic admits he's disappointed with the way he's been treated by coach Ronald Koeman.

"Man to man, he spoke with me in December and said things that soon were not fulfilled. I only say to him that he has not seen the true Nikola Zigic at Valencia," said Zigic.

"I have hardly spoken with him. I'd like him to tell me what I have to do to get a game."
