Croatia and Nigeria meet for the first time in Kaliningrad tonight at 8pm in a World Cup clash that could prove crucial to their chances.
Nigeria, the lowest-ranked side in Group D, reached the World Cup last 16 in Brazil four years ago but come into this tournament having failed to win any of their last four friendlies.
However, manager Gernot Rohr has hinted he will revert to previous formations to help the Super Eagles seal a victory.
"We were trying out different formations but we are going to switch back to the way we played over the last year coming to this World Cup. If we do exactly what we know we can do, to control the game and be aggressive, we can do well," he said.
"Our players have a lot to prove and this is a very good stage for them but it’s also important to keep their emotions in check. We are staying humble but we are also ambitious and if we are to get out of this group, we have to make a result against Croatia."
Croatia boast the likes of Luka Modric and Ivan Rakitic in their ranks but failed to progress from the group stage in Brazil and needed a play-off to reach Russia.
But manager Zlatko Dalic is confident he has the perfect mix of youth and experience this time around, saying: "We have a very good set of players who are the driving forces of big clubs and young players – it’s a good mixture of youth and experience.
"It is right that expectations are high and we expect from ourselves more than anybody else. I hope we will prove all those flattering epithets right and that this generation will get a result with some luck along the way. We are full of self-belief and ready to show some good football."
Argentina are hot favourites to win Group D and with Euro 2016 quarter-finalists Iceland potentially awkward opponents, both sides will aim to boost their hopes of progressing with three points by the Baltic Sea.
Nigeria will face Argentina for the fifth time in just their sixth World Cup finals appearance in Russia, and they are yet to win a single one.
Team news
Question marks remain over Croatia’s left-back position, though Ivan Strinic is being tipped to get the nod, as well as how best to deploy versatile forward Andrej Kramaric.
Injury forced Moses Simon to pull out of the Nigeria squad ahead of the tournament, although Leicester midfielder Wilfried Ndidi is fit to play despite some concerns over his inclusion.
