I was thinking this, AWB attempts to get the ball sliding in front of Soucek and misses it but Soucek actually comes in from behind AWB and falls into AWB also missing the ball,AWB was actually the right side of the Soucek to make the challenge and slid in front of him as they both attempted to reach the ball and both failed. The contact was absolutely minimal and not enough to bring him down. Look for yourself:
Soucek basically just leaned into the challenge and folded his legs.
It's extremely convenient for pundits these days to just completely ignore the most obvious of points that need to be referenced if it doesn't fit their agenda or there just plain thick , probably the latter tbh but it's infuriating
