When they were behind and started that desperate play to get the game back to par they performed much better than the previous 70 minutes they played lol.
I assume that they thought that their next targets are Belgium and Algeria and they are more confident that they can win against them

That said they are in 3rd place in the standings so they need to work harder to win this can't just play cautiously against the strong teams.
Hmmm... their passes were extremely inaccurate. Check the performance of Yuri Zhirkov. Accuracy of only 71%. WTF? Yes. They played too defensively. A reason for that is the attacking players (Kerzhakov & Dzagoyev) were kept in the bench by that idiot coach.
Your right they were inaccurate and that was probably the Coaches fault, anyways this game is settled for now we will need to see if Russia can win the next few games to keep in the game.
