Ayila Yussuf criticises referee following 2-2 draw with South Korea...
Yakubu spurned a glorious opportunity to level the scores with the game standing at 2-1, directing his shot wide when he was presented with an open-goal, inside the six-yard box.
The Everton man then went on score a penalty, but with Nigeria were unable to find the winner that would see them progress from Group B.
Speaking after the match, the former Arsenal man conceded: "As a striker I think that's the easiest one to score, so if you miss it then I don't know what you will do," Kanu said of Yakubu’s miss during a post-match press conference.
"If we didn't create the chances we'd complain, but in fact we made them but didn't take them.
"The fact is that we played South Korea, a very good team who worked very hard, and we didn't take our chances."
Meanwhile, midfielder Ayila Yussuf has criticised referee Olegario Benquerenca for his handling of the match, insisting that he was treated unfairly during the match, after receiving a booking in the first-half.
"I know him very well because we've met so many times in the Champions League,” said Yussuf.
"I asked him 'why are you like this with me?' and I spoke with him about it and he said everything was alright."
