GIF Shows Demichelis Challenge Clearly Started Outside Box

It look just eight minutes of the second half for Barcelona to go ahead, thanks to a Lionel Messi penalty. Martín Demichelis was sent off for the challenge but was it actually outside the box?

From the gif it seems pretty clear the first contact was outside the box and Cork Gaines shows the same from another angle.
