The spin of the ball can be seen from any angle where the ball is visible, you don't need a top view to judge it. This is what we use all the time to judge if a GK got fingertips on a shot.
If you combine both angles there is no scenario where the ball could "slide down his arm": he's running onto the ball, it bounces off him, you can see it on the face shot. The ball can't both bounce and slid at the same time in that particuliar action. If it did the ball would not go this far in front of him unless he "poked" it.
You can prove he's wrong with basic physics and combining what you learn/see from each angle. It's a deduction with 2/3 angles. You can argue the semantics of the conclusiveness of deduction logic but one scenario is largely more probable than the other.
I'm not discussing the assistant right or reason to make the call from his position, only that since you say it can't be proved he's wrong and it can't proved he's right: he clearly guessed.
I'll leave you with that, feel free to still disagree, i've watched that replay 50 times now, my eyes hurt
He's there to make a decision in a millisecond. From his angle, and those first few replays they showed, it looks like he handballs it. Players think so too. Bam, he waves (a fictional flag) and tells the ref there's handball . The ref will absolutely take this cause the alternative is way more dangerous and crippling; he could send a player off when there's no proof that the Bayern player didn't actually handball it. VAR is of no use here of course. I'll still disagree about combining angles to be proof, fair enough. But do go watch some gifs of rainbows or something now, this shit ain't worth it.
Bless the yanks and their terrible football takes. He was booked for handball. After flinging himself to the ground and grabbing the ball. Defenders have a right to stand their ground. They can’t vanish when an opposing player runs straight into them.
