What about the Diaz thing?
Unless it was found to be due to corruption the result will stand. The two VAR officials might never have that role again and could possibly be stood down as refs. I reckon PGMOL will have already distributed a new communication protocol around offsides. All they have to do is change the advice to the ref to something like "Check complete. Onside/offside". At some point they will probably move to releasing the audio every time.
