After the Italy-Australia match, with the wrongly called penalty in the 93rd minute, I fear it's time for video replay, and mandatory consultation by the ref with the AR and someone who is watching the video. The faking and cheating are overwhelming the refs. I think I'd probably use video for PKs, red cards, and goals where there's any dispute. Maybe disallowed goals as well, like the wrongly disallowed goal in the 90th minute in Argentina-Mexico, wrongly called offside. That could have given the game to Mexico, as the wrongly called PK gave it to Italy. The integrity of the game is at stake. If these refs, the best in the world, can't keep up, then other measures are called for.
