Personally, I thought we saw our best 2 referees in the televised games today, though with different styles and approaches. Anthony Taylor issued plenty of YCs but as far as I could see all were justified and he was consistent. Excellent mobility on the pitch.
Perhaps more surprisingly, Michael Oliver decided to manage the game to give it a chance and while the 2 challenges referred to could (some might say should) have drawn cards, he opted for a stern warning which seemed to have the desired effect. We can argue about the handball(s) till the cows come home but I thought he showed a lot of maturity in the way he handled the game. Maybe he was too understanding of City's frustration in being lenient with the dissent but personally I'd be very happy to see high profile games like that with such intensity refereed to that level of performance. And like Taylor, it's very impressive how he can get into good positions even from fast breakaways.
I can perfectly understand why Oliver and Taylor are our 2 FIFA elite referees.
