"Our style was cramped a bit and maybe we did not want to risk with passes, so we had to balance it out in the second half", the Real Madrid man said. They are still great guys for us, they are heroes.

Subasic saved the first attempt of the shootout when he made an adjustment while diving to get a hand on Fyodor Smolov's attempt.
For all of Russia's hard running, it was unable to prevent the equalizer just eight minutes later.Mario Mandzukic's powerful run down the left was followed by a deft chip into the box, which the onrushing Kramaric diverted past Igor Akinfeev.
