They're officiated better because they have help. In general, English refs are not better or worse than any other refs. But when you have one chance to make a decision, mistakes will be made, so refs then look worse than they are, when it happens. Now they can see everything they need to look at when they have to look at it, as many times as necessary.
With the biased LFC hat on, I'm looking forward to all the extra goals penalties and points we're set to get, that we didn't before. We got our first of many in Porto. I'm also looking forward to the team going to the toilet, and not been terrified of what the ref is going to do anytime the mancs get near our box. If the cost is an extra minute or two injury time, I can take it.
