At one point considered to be among Serbia's brightest footballing talents, Ognjenović signed with European giants Real Madrid in his early 20s, but never became a regular there, despite winning major titles, eventually going on to have an irregular career in six other countries.
[3] Ognjenović's time in the Spanish capital was not a happy one overall: only after manager Guus Hiddink was replaced by John Toshack late into the 1998–99 season did he make his official debut with the Merengues, appearing as a second-half substitute in the Copa del Rey semifinal clash against Valencia CF (2–1 home win after a 0–6 away loss).
FC Kaiserslautern arranged a tryout and brought him in for free on 17 January 2002, in a deal until the end of the campaign with a two-year extension option;[7] they finished seventh in the Bundesliga and qualified for the UEFA Intertoto Cup, but the player only appeared twice.
After failing to settle in Germany, Ognjenović's next stop was China with Dalian Shide FC, where he was brought to in January 2003 by the club's coach Milorad Kosanović, who had already managed him at Red Star.
He then moved on to FC Dynamo Kyiv in late November 2003,[8] but could not earn playing time there either; the next stop was in France, as he signed in January 2005 with Angers SCO in Ligue 2.
