It's on Amorim and the club. Narrative shapes FA and PGMOL policy. It's a game Fergie, Klopp and Mourinho excelled at, and we've simply stopped in the past decade.
Were it me, I'd have Amorim's press conference tomorrow focus on the WHU decision, and how it was so bad it made the news even in Portugal, and how it's very strange to him how the PGMOL would reward that kind of mistake with the highest profile match in the country. And then bring up that when they heard, Dalot showed him the clip from last year and he found it even more bizarre, that such a referee could face no repercussions. Just asking questions.
Play the game. Staying silent gets us bad decisions each and every week.
