Experienced striker Yakubu Aiyegbeni has admitted that the Super Eagles, recently crowned African champions, have a busy fixture schedule this coming summer.

In June, Nigeria will play a World Cup qualifier against Kenya and days later participate in the Fifa Confederations Cup, where they are pitted in the same group with Spain, Uruguay and Tahiti.

Aiyegbeni, these days playing for Chinese club Guangzhou R&F, has warned the Nigeria selection not to approach the upcoming matches with kid - gloves.

''The January's Cup of Nations has shown that in Africa no team can be underestimated.

''Kenya will be keen to win the games and we should prepare carefully. An opening victory against Kenya will be a timely boost for us ahead of the Confederations Cup,'' says Aiyegbeni to fifa.com.

Speaking on the Confederations Cup, the last time Nigeria participated in the tourney, the team qualified for the last four. And Aiyegbeni is hopeful the National Team can better that record in Brazil.

The ex Evertonian told the official website of Fifa: ''The team travel to Brazil on the back of the Cup of Nations success so they are inspired to put in good showings on the world stage.

''I am confident our side can live up to the expectations. And above all, we will qualify for the next World Cup.''
