The 22-year-old striker is due to play for Nigeria in a friendly against Ghana at Brentford's Griffin Park early next month. Ghana cannot insist hre plays, so Glenn Roeder wants him to side with those who pay his wages.
Martins Must Decide
Roeder: "It is only a friendly and Nigeria cannot insist on Oba playing. And because he has had so much football this season I will be asking him not to play against Ghana.
"He has already played nearly 30 games for us, and he has probably played more matches this season than at any time in his career.
"He is a great lad and I am sure he will understand the situation because we are a bit thin on the ground for strikers and we do not want the risk of losing him."
