Russia, who finished second in Group A will face Group B winners Spain in Moscow on Sunday. They could have played Portugal in the last 16 but Fernando Santos's side finished second behind Spain on goals scored.

"There is no difference, Portugal and Spain have completely different styles of playing. It's not so obvious whom it would be more difficult to face. We'll try to exploit Spain's weaknesses, if there are any, of course. Our task is to prepare well and to play at the maximum of our abilities. We'll run even more and exert even more pressure on them if we need to," Ignashevich told journalists.

The 38-year-old added that Russia would namely exploit Span's tendency to leave free zones in their half of the pitch.

According to him, the fact that the match will be held at Moscow's Luzhniki Stadium was "the only advantage" of being the Group A runners-up.
