As much as most of us are biased (obviously) it's hard to tell imo how the actual facts fall. I'd love a neutral party to weigh in. From my perspective, between Casemiro and the way our 50/50 or 'seen them given' penalties have completely dried up versus Pool getting quite a few, it feels like this season has been particularly harsh on United, and lenient on Liverpool. But I don't watch LFC matches in their entirety, so I don't get a feel for the balance of missed decisions.
The simple truth is that the media makes more money if bad things happen to Manchester United. If we were having the season Chelsea are having you probably wouldn't know there's a tight relegation battle, you'd only know Haaland is doing well because he almost came to United and you'd have no idea about the Top 4 because the media-gasm would be non-stop. Article about United getting preferential treatment from a ref? Simply gets more clicks than an article about United getting screwed. It's the burden of being the best in the formative years of so many people.
I posted a thread about 6 months ago that this partly falls on ETH and the rest of the club. I hate the fact that referees - consciously or unconciously - feel it's easier to give decisions against us than for us if they're tight. I can do nothing about that. Fernandes, despite all his yelling, can do nothing about that. The media control this sport, it's a media-created entertainment product. ETH has direct access, and the club has indirect access. We HAVE to start using this channels if we really believe we're being disadvantaged.
What Klopp has achieved with his penalty comments is utterly brilliant. It's probably cost us close to 10 points since he gave the interview. It's exactly the kind of thing Fergie would have done.
When Casemiro got sent off for the first time, much less the second, I want ETH up there for 2 whole minues, staring calmly into the camera, asking why there is one rule for one player, and a different for another. I want him to interupt the next press conference question about Rashford's fitness, and instead ask the press if they've heard yet what the difference between, say, the Havertz challenge and Casemiro's red. And then ask if they've heard between Fabinho's and Casemiro's. I want him creating headlines which puts pressure on referees not because I believe it should be effective but because I know it IS effective.
Hell, before the LFC game I would have had thoes penalty stats to hand re Klopps comments. And I would have had the lack of penalties and red cards at Anfield in the last decade too. Football is narrative, and we're too passive. And it hurts on the pitch.
