not sure what Hummels is supposed to do with the follow through? It’s a natural movement. It isn’t violent, he doesn’t catch him with his studs.
Only way to stop that is to tell defenders they can’t go to ground anymore, and give free kicks if they do?
Is that what they want to happen? It’s never a penalty. I hate the ‘game’s gone’ phrase, but honestly, I’ll allow it for that if people find it acceptable to give penalties for that sort of shit!
