Nigel Worthington believes his team's South Africa 2010 qualifying campaign has been a success, with Northern Ireland finishing fourth in Group 3.
Switzerland and Slovakia seized Europe's last two automatic berths in South Africa, while Portugal, Greece, Slovenia and Ukraine made the play-offs.
Slovakia won 1-0 away to Poland to secure first place in Group 3 and a berth at the FIFA World Cup for the first time since gaining independence.
Northern Ireland earned an impressive goalless draw away to Czech Republic to round off what has been an admirable qualifying campaign.
Defender Marek Jankulovski said he was quitting international football after the Czech Republic lost all hope of qualifying for South Africa 2010.
Slovenia cruised to victory away to San Marino, but were forced to settle for a place in the play-offs courtesy of Slovakia's 1-0 success in Poland.
