German Bundesliga side, FSV Mainz, appears to have baulked at the idea of releasing striker Anthony Ujah for the 2012 Olympic qualification.
Ujah, 21, said that his employers have grown cold on the matter.
The former Lillestrom man said he will press further by explaining the importance of featuring for the Nigerian Under23s at the Olympic qualification in Morocco but will not force the issue.
"I spoke with my club officials after the (Under23) coach (Austin Eguavoen) came here to speak with them. That was two weeks ago before the cup game against Hannover.
"But I think my recent performances for the team may have brought about a re-think. They (Mainz) are not saying anything and I feel they need me now (to stay back) after I scored my first goals against VfB Stuttgart last week.
"Seriously I can't do more than I've done because they have the right as my employers to keep me. They've been very good to me since I arrived here and I have to be very professional in doing my job too.
"I really will love to play for my country but my club is also struggling right now and need me so badly. But I'm still hoping that they will give me a chance to add more to my caps," Ujah said.
Nigeria's Under23 Eagles have been drawn in same group with hosts, Morocco, Algeria and Senegal for the 2012 Olympic qualification.
