Russia would have to "fight to the death" in order to win the FIFA World Cup round of 16 match against Group B winners Spain, the team's striker Artem Dzyuba said.
The game between hosts Russia and 2010 World Cup winners Spain will take place at Moscow's Luzhniki Stadium on Monday (12am AEST).
"Each of us will have to fight to the death on the pitch - 95 minutes, 100 minutes, whatever it is, we'll just have to give it our all" Dzyuba was quoted on the tournament Twitter account.
"The interesting thing about football is that any team can beat any other on the day. So if we all go there and give not just our best but 200, 300 percent more, I believe we have a chance create this historic moment."
The player also expressed hope that the "football gods" would be on Russia's side because a little bit of luck would definitely not hurt in the match against Spain.
The 29 year-old has scored two goals and made one assist at the tournament so far.
Russia finished second in Group A and advanced to the knockout stage of the World Cup for the first time in history. The tournament will continue until July 15, with the games being played in 11 cities across Russia.
