Yeah, I'd be interested to know who got booked for that as MOTD2 didn't show anyone. Dier certainly should have gone in the book for choosing to celebrate in the way he did.He's always been Mr unflappable, total calmness today when everyone else lost their heads.
If I was being critical I would say there should have been more than one caution for the mass conf following Dier's goal, even if for a sub. Lichsteiner appeared to cause it by grabbing hold of Dier, but I only saw the one card. But overall he was superb.
