I don't think that is correct, dangerous play is a booking, contact or not, happy for you to quote the exact rule though, if you can find it.
I'm pretty sure though that Silva's booking was before the penalty, not after, as has been claimed in this thread, and at no point does he do anything aggressive in the coverage I've watched, and as captain he has the right to ask for clarification.
Nowhere do our players 'lose control', it all looks quite mild, which is why I think its a joke we have been charged.
The only person who lost control yesterday was Oliver.
