Nigeria striker Odion Ighalo says Tuesday’s decisive World Cup Group D clash against Argentina in St Petersburg will be “a war”.
Argentina must win to reach the second round while the Super Eagles can qualify with either victory or a draw.
“It’s going to be war (and) a final of finals because they need to win,” Ighalo told BBC Sport.
“They are going to come all out and (use) every tactic that they know to win a game.”
The clash between Argentina and Nigeria will be the fifth World Cup meeting between the sides – with the Super Eagles yet to avoid defeat.
With maximum points in Russia following wins over Nigeria and Argentina, group leaders Croatia have already claimed one of the group’s berths in the Round of 16.
That has left Nigeria, Iceland and Argentina – runners-up at the 2014 World Cup – scrapping for just one place.
