Russia coach Guus Hiddink has demanded an improvement after accusing his players of giving Spain 'gifts' in their opening 4-1 Group D defeat.
Russia take on reigning European champions Greece in Salzburg on Saturday knowing anything other than a victory could bring a premature end to their European Championship campaign.
"You could say we took our wallets out of our pockets and gave them to the Spanish team," claimed Hiddink.
"We were too nice and gave them gifts. We were childish and naive in falling for their counter-attack ploy.
"We weren't outplayed - we gave the game away. We need more experience and to learn very quickly.
"For most of the players it's their first appearance in a major tournament."
