The Danes lost 3-2 in a penalty shoot-out after it finished 1-1 after extra time in Nizhny Novgorod.
Christian stepped up first in the shoot-out and struck his effort well only to see goalkeeper Danijel Subasic touch the ball onto the post.
That was the first of three penalty saves from Monaco number one Subasic, the third setting it up for Ivan Rakitic to slot home the decisive spot-kick for Croatia.
