I'm sorry. You try to be a reasonable poster but you can't seriously think the laws of the game say possession goes to the team without the ball after a stoppage. If you do really think that, you shouldn't be on a football forum at all, because your views are worthless. At best, it was clearly a big mistake by the referee. At worst, it was a deliberate mistake.
And that nonsense about evening up. You honestly don't see a difference between an incident in the middle of the game, and one in the last minute when one team is trying to keep possession desperate for a point after 100 minutes hard work and the other is looking to counter, desperate for two extra points? Stop drinking Klopp's kool-aid.
