2 out of 7 in the box appeal - the rest don't at all. Stonewall pen you should do stand up!
The stonewalledness of a penalty is completely unrelated to how many people claim for it, especially when the ball, and therefore the focus of the opposition players is right in front of the goal.
There is that cliche "play to the whistle", if players do that, as four of those seven were (while one was lying on the floor after the challenge), referees can't then just ignore what they believe are fouls because not enough players saw and claimed for them.
I've only seen the angle on the highlights, I don't know if it was a penalty or not, I'm just pointing out the gaping flaw in your apparent logic.
