The Super eagles are currently leading Group B of the 2018 World Cup African qualifying zone with six points after winning their first two games against Zambia and Algeria.
Despite this good form, NFF chiefs are still not yet okay until they qualify for the 2018 showpiece in Russia.
Media officer of the super sagles Toyin Ibitoye explained that Gernot Rohr has a mandate given to him by the Nigeria Football Federation (NFF) and it would be disastrous if he fails to deliver.
''The mandate given to Rohr by his employers is for him to get Nigeria the 2018 World Cup ticket, and failure to do that means he would have to go,'' Toyin Ibitoye said.
Nigeria would face reigning African champions Cameroon who are second on the table in their next game in Uyo on August 28 with the return leg five days later in Yaounde.
