I hadn't seen Beaton before but was very impressed. What is his background/age? Does he have any prospects on the international scene?
I thought Oliver generally did well although I thought Arsenal should have had a penalty with the benefit of the replay.
I was impressed with Beaton until later on in the game. Morelos was somewhat fortunate to be still on the pitch at the end in my opinion.
Personally I thought Oliver was very good and his positioning and movement excellent. As for the Arsenal penalty claim, they said on btsport there was sufficient contact, especially as the Arsenal player was running at pace, and it should have been a penalty. Maybe it should be specsavers for me, but having seen the incident and full speed and slo-mo several times I was struggling to see the contact but I was looking primarily at feet.
I thought the 2 Liverpool penalties were justified and correct, the second one looked clearer from a different camera angle and Oliver had the better angle too.
