Nigeria coach Lars Lagerback was extremely disappointed with the Super Eagles' failure to qualify for the second round, as he believed his side deserved better.
The Africans could only manage a 2-2 draw with South Korea, which meant that the Taeguk Warriors progressed to the knockout stage of the tournament.
Nigeria had opportunities in the second half to secure their progression to the knock-out stages, but Yakubu, who later scored a penalty, missed a glorious opportunity for the African side, before Obafemi Martins chipped wide after coming on as a substitute.
"I'm very disappointed because I was convinced we deserved more in the World Cup," the Swede said post-match to AS.
"At all times, we continued to fight, to achieve progression, but unfortunately it was not enough."
