That isn't how VAR works, or at least not how it should work. They tell the referee there may have been an error and why, they show him the footage supporting this, but if he chooses to ignore their advice it isn't down to them to talk him round.If the VAR is anything like I've listened to in the EPL games, then surely they should be ending the chat with a clear decision and agreement.
Surely VAR should be saying "I don't think you're seeing this right. Have another look..."
How VAR has allowed him to walk away knowing he still has it wrong. So wrong. I get referees decision is final etc, but this is just plain stupid.
