This trailed his leg out argument is quite a lot of bollocks to be honest. I'm not saying he wasn't looking for a penalty with the fashion of how he fell, but neuer literally sticking his leg out unnaturally to bring him down is a much bigger deal. That's the primary, and Sakas legs were not unnatural, he was cutting left to run, he got caught and it was enough to bring him down.
This AFTV and Ian wright argument is also weird. If you heard commentary, Rio and Keown said its a clear foul, and the pair of them are center backs. What's your point?
