I don't understand the controversy. Mings plays the balls so the player is not offside.
It is not complicated and I thought this was settled ages ago.
Ferdinand is a prick calling out the ref, he is following a simple "law".
I think some of the controversy is that City scored from the call and many did not want City to win so their bias is coming out.
You are right Mings clearly plays the ball so Rodri should not be offside.
I doubt we would hear much outrage if the teams were reversed, or at least not as much outrage.
