I liked his 'no goal' signal.
Given we've seen slo-mo replays stuff referees up with the on-field review in Australia, I wonder how much training those referees are going through in how much slo-mo distorts things?
Also, it looks like the VAR is providing the angles for the referee to look at. This seems like a potential problem as the VAR has seen the full context of the incident, but puts a very selected view to the referee. If this is only slow motion, can this skew the referee's decision when the VAR has the more holistic view?
