Croatia can feel very aggrieved. The first goal shouldn't have stood, and I think for two reasons. The obvious one that there is no way it was a foul for the free kick, so that should have been reviewed. Then I also think there is a very possible offside on the goal - Pogba is stood offside and challenges Mandzucic as he heads it.
For the penalty I'm hot having that as intentional. He was jumping so yes his arms were out, and they were coming back down as the ball hit him. I've said this so many times, but you cannot jump like a penguin with your arms pinned by your sides.
