Celtic target Henry Onyekuru has blasted his club Eupen for blocking a transfer to the Scottish side and accused them of trying to force him to move to CSKA Moscow.
Sources told ESPN FC on Wednesday that Onyekuru, 19, is unhappy Eupen have gone back on a promise to let him leave in January, while trying to push him to work with an agent who has close connections with the Belgian club.
Eupen have rejected a bid from Celtic for Onyekuru, with the club's chief executive Christoph Henkel aiming a swipe at the Bhoys' attempts to sign the Nigerian striker by suggesting he is too good for Scottish football.
Onyekuru has been left frustrated by Eupen's actions, alleging they want him to work with another agent and not his agency Macato Sports.
"Eupen are acting funny on my transfer. They are frustrating me and my agent for their own interest," Onyekuru told AfricanFootball.com.
"They promised to let me move in January if I have a good offer. Now there are good offers but they now want me to sign for their own agent before I move, and they want me to sign for CSKA Moscow which I am not interested in. This is unfair and not acceptable."
A number of Europe's top clubs are tracking Onyekuru, with the youngster having caught the eye after scoring 12 goals and registering six assists in 22 games this season for Eupen.
