Yes. You can actually see the attacker pushing McTominay in the face right before the dive. The psychology being, that McTominay wouldn't let him go but couldn't see him so he stretched his arms out, that's when he fell. Right before that construction, they both held each other, even a hand to the face which definitely isn't allowed.
Why wouldn't VAR review it and look for something to overturn it, like the hand in the face just a moment before. If McTominay went to ground holding his face, it just wouldn't be a foul. The precedence they are setting is terrible for the game as cheating is beneficial.
It's like a touch is enough to get a penalty, put when we get fouled and nothing gets given I constantly hear excuses from people commenting like "soft" and 'shoulder to shoulder', 'wasn't enough in it', 'he went looking for it'. Yet now it's totally the other way around, they have excuses for why it should be given. 'McTominay is clumsy or stupid doing that'. I remember they did my boy De Gea dirty a few seasons back, totally crowded him and pushed him around and refs and media just decided he was weak so it's okey.
No, it's a fecking foul, and this was too because you can't put your hand to the face of a player.
