Yeah, you've said. Lots.
It's still a foul.
It's an absolute bullshit decision, yet again. Every single match.
Refereeing decisions can go against you.
Stuff like fouls on defenders and goalkeepers are fatal. This one isn’t 100% a foul. Even Rafa doesn’t think it’s a foul. In these instances you need your player to be strong and only be beaten by a massive foul/incident.
Some arms on him. No body. No push. Boly wanted it more and he did so fair enough imo.
Your post is fundamentally wrong man.
1) Rafa said the refs don't know the rules in England, implying he felt it was a foul. He even motioned it as such after the match.
2) Dubravka went up with 2 hands to catch and Boly went up and used the face/shoulders of Dubravka to gain leverage to get higher and move his head back and body back. Look at pictures if you didn't already. It wasn't some arms, arms change just as much leverage as anything else, he climbed on him.
