Bob Osim

Osim played on loan from Iwuanyanwu Nationale for Enugu Rangers in the 2003 CAF Cup. He was named man of the match in the quarter final first leg 4–0 victory against Egyptian side Al Ahly. He was among a number of players who alleged Iwuanyanwu owed money for unpaid salaries in 2004, for the previous season. In February 2004, he was among 47 players signed by Enyimba International. Shortly after his arrival at the club, Osim scored the only goal in the 2004 CAF Super Cup, in which Enyimba defeated Étoile Sportive du Sahel, becoming the first team from Nigeria to win the competition.

Internationally Osim played for Nigeria. He made his first start for his nation in a 1–1 friendly match draw against Egypt at Lagos National Stadium in November 2002. Osim played the full 90 minutes of a May 2003 friendly match away against Jamaica, which finished 3–2 to the hosts. In July 2003 he was named in the squad for a friendly against Venezuela. At the end of that year, he was part of a pre-tournament 41-man camp in Portugal ahead of January's 2004 African Cup of Nations, although he wasn't part of the final 23-man squad. He was called up in 2006 for Nigeria's 2008 Africa Cup of Nations qualification match against Lesotho.

Osim was announced as the head coach of Calabar Rovers in January 2019.
