That was not a yellow card, bad call by the ref.
How stupid it was going in like that by Turan is irrelevant, as the contact made was not enough for a yellow. He pulled back, no straight legs, barely any contact and both going for the ball.
Seen loads of yellows for challenges like that when player arrives late with high foot.
Silly challenge to make and risk a second yellow.
You fucking dumb Oblak
I agree it was silly, but it doesn't matter as the fault lies with the ref for not making the correct call. Objectively speaking of course. Turan made a mistake doing it, that's for sure.
