This was always going to be a tough game to referee and whilst there were plenty of positives (e.g. fitness, positioning, sanctions), I think there were some issues / points for consideration:
Penalty not awarded to Wrexham for a push by the NC4 on W10. I think this was clear.
Question mark over the first Wrexham goal and a possible foul on the defender (although on balance I think it was probably correct to award the goal - there was nothing conclusive to show a foul)
I am not sure who has seen the handball and have a feeling there might have been input from one of the other officials to get the decision correct. You can see the referee moving backwards away from the penalty area after the incident / as the ball starts to break which wouldn’t be the natural movement if the handball had been seen. That said, the most important thing of course is that the officiating team have got the decision correct.
As mentioned by others, some debatable offside decisions from the ARs.
Overall, I think the team will be pleased that the focus of discussion after the match is on what a great game of football it was and not on them.
