Striker Nikola Zigic joined Blues in May 2010 on a four-year deal from Spanish La Liga side Valencia.
Less than a month later he linked up with the Serbian squad for the 2006 World Cup Finals in South Africa.
It was the second time that Zigic had appeared in the finals, having previously represented Serbia and Montenegro before their split, during their 2006 campaign in Germany.
The 2010 finals were the first time that the World Cup had been staged on the African continent and included participants from 32 nations.
Serbia were drawn in Group D alongside Ghana, Germany and Australia.
After the disappointment of losing their opening group game, they returned to winning ways next time out with a 1-0 victory against German
y on 18 June at the Nelson Mandela Bay Stadium in Port Elizabeth. Milan Jovanović's goal secured the three points and Zigic completed the full game.
They went into their third group fixture as strong favourites against Australia on 23 June, but somewhat surprisingly they were beaten 2-1 by the Socceroos
at the Mbombela Stadium in Nelspruit. Zigic played 67 minutes. That result saw them finish bottom of their group and bow out of the tournament at the group stage, as they had done four years earlier.
The tournament was eventually won by the reigning European champions Spain, who beat the Netherlands 1–0 after extra time, thanks to Andrés Iniesta's goal to earn them their first world title.
