"I have the same expectations as before our match against Spain. Our players will have to give 200 percent to win, otherwise it's not going to work. Croatia are not at all weaker than Spain. In terms of style, the game will be different, but in terms of strength, these teams are comparable," Dvorkovich said.

After beating Spain 4-3 on penalties in the round of 16, Russia will take on Croatia, who also beat Denmark in a penalty shootout, in their quarter-final match at the Fisht Stadium in Sochi on Sunday (AEST).

The 2018 FIFA World Cup kicked off on June 14 and will continue until July 15, with the final set to be played at Moscow's Luzhniki Stadium.
