Career
Born in Yaoundé, Ovono began playing football in Europe in Turkey, starting with modest Sivasspor, then switching to the Süper Lig in the 1997-1998 season, appearing very rarely for the last-placed team, Belediye Vanspor. In the following decade, almost uninterrupted, he played in Portugal, mostly in the lower leagues. After a very brief spell in Greece, he resumed his career in the country, appearing for seven different clubs (notably Portimonense South Carolina, when it was in the third level).
In 2001, Ovono had an unsuccessful trial at 1.
Football Club Union Berlin in Germany. After returning to Portugal, he eventually retired at the age of 33, his last club being Grupo Desportivo Sourense, in Soure.
