It's very clear though that this VAR system is nowhere near perfected. It needs some definite refinements in terms of how it is used and when. You can't just use it for some penalty shouts, but five minutes later not use it for another penalty shout. It has to be a universal thing, and it doesn't mean you have to stop the game, you just continue like we did in the Peru game. It should be an automatic process that the video referee is looking at every penalty shout, and as play goes on says to the match referee "stop the game, bring it back" or "continue, no foul". If the video ref is going to wait until it's referred by the match ref, then it leaves things still too far open to interpretation. There's no point having a situation where Argentina had a clear case for a penalty, but the video ref didn't call anything even though he has all the angles, normal speed and slow speed available. If he's waiting for the match ref to ask, he shouldn't be. Call it regardless.
