Besides the obvious that City won and had a clean sheet, I found it to be a thoroughly enjoyable match, compared to many other matches.
No timewasting (yes, Ortega got a yellow for it, but that's normal for City, and one time O'Reilly went to the corner), surely helped by City taking the lead early. Not many situations of diving to "earn" a free kick, no niggly tackles, no snide actions, no handbags.
This is how every match should be.
Edit: Oh, and very few, if any, VAR delays
