My overall impression is that whilst mistakes are still made the officiating has allowed the games to flow, they seem to be accepting that it is a contact sport and just wave the game on whilst the players just lay on the floor then suddenly arise like Lazarus !!! In the EPL they would without doubt whistle for a foul.
As for VAR, whilst I understand there was a long delay last night in the main there lack of intervention has been a godsend. Rather than forensically examine every move in the previous 5 mins they have gone with the refs decision, something the PGMOL could learn from.
In my opinion the officials in the World Cup have improved the spectacle of the game
