Under-fire Australia boss Eddie Jones has called for rugby to use technology less and have the TMO involved in fewer instances.
Jones wants play to be sped up as opposed to continuous pauses for TMO, something the bunker system was designed to help address at the Rugby World Cup, but Jones thinks that more change is necessary.
“We have got so many stoppages now, we had a TMO for everything,” said Jones.
“We need to make the referee the sole judge of the game. If there is something that is an obvious red card then go back to that. We have got to keep the game moving.
“I think part of it [fans booing] is because there is so much discontent with the flow of the game. I don’t know how many minutes they spent with the TMO deliberating on a possible Portugal maul try.
“It was obvious it was a no try, so why do we have to watch replays and replays of it?”
