Kanu has pointed the finger of blame at Yakubu for missing 'the easiest chance to score a goal' in Nigeria's Group B decider against South Korea on Tuesday night.
The Everton striker somehow fired wide of an open goal from five yards out shortly before making it 2-2 from the penalty spot.
That's how it finished, leaving the Super Eagles bottom of the group and on their way home. Had they beaten South Korea, however, Nigeria would have qualified for the last 16 and Kanu is rueful of Yakubu's miss.
"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," said the Portsmouth player.
"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."
