Guus Hiddink has admitted he is leading an unknown quantity into action as his Russia side prepare to kick-off their Group D campaign with a clash against Spain.
Russia's lead up to their first game has hardly gone smoothly with playmaker Andrei Arshavin suspended and leading scorer Pavel Pogrebnyak ruled out of the entire competition through injury.
But Hiddink is hoping an attacking philosophy can help his side upset their more fancied rivals.
He said: "I am very curious because it's the first time they will act on a huge stage.
"I want them to go out and play good football, I want them to make Spain's life very complicated.
"I don't want the frightened and timid performances of some previous tournaments.
"Very few of my players have top-level tournament experience but they've reacted to the hard work I've set them.
"Our intention is to break the pattern so far where the favourites have always won."
