Kenya's football federation (FKF) says it is still to hear from McDonald Mariga after attempting to play down a rift with the star midfielder.
Last week, FKF chairman Sam Nyamweya wrote to Mariga to try to "resolve outstanding matters" after the Parma player boycotted the 2013 Africa Cup of Nations qualifier against Togo.
Mariga walked out on the eve of the 2-1 win in a row over unpaid expenses.
"The ball is in his court," says FKF secretary general Omondi Aduda.
The FKF has requested that Mariga forward copies of air tickets and other receipts so that he can be paid some US$20,000 he says he is owed from previous national team trips.
"Up until today, Mariga has now forwarded the invoices to the federation and has not replied to the chairman's correspondence, so we are waiting."
"As of now, there is very little we can do about it."
"He may be busy and I don't want to pre-empt what is happening, but as a federation we have done our part and we are waiting for him to do his."
"Somewhere in the middle, we will meet to hopefully sort out these problems."
Aduda added that it is up to Kenya coach Francis Kimanzi to decide whether he wants Mariga, elder brother of Celtic starlet Victor Wanyama, to contest Kenya matches.
