Strikers Emmanuel Dennis and Victor Osimhen say Nigeria players are prepared to leave "their blood and sweat on the pitch" ahead of the return leg of their World Cup play-off against Ghana on Tuesday.
The first leg in Kumasi ended 0-0 which leaves the Super Eagles needing a home win to reach Qatar 2022, which would be their fourth global appearance in a row.
Watford's Dennis and Napoli striker Osimhen, who both dropped out of Nigeria's squad for the Africa Cup of Nations in Cameroon, are determined to be at their first World Cup with the Super Eagles.
