I did watch it. You could see Vertonghen's head vibrate from the contact. Whatever way you dice it he headbutted him.
I wouldn't disagree with either of you, but Vertonghen is a tosser because he deliberately tried to get him sent off. If I'd been the ref I'd have booked him, then sent him off the next time he did anything resembling a bookable offence.I'd watch the replays again. By the looks of it he was reacting to Vertonghen pushing into the defensive line during the free-kick, so he gave him a little nut. It's not a big one, but there's definite movement and he deserves to go for that. He went barmy because it was admittedly soft...but the rules are rules.
