I think I’ve mentioned this before somewhere on this sub but I think across Europe all leagues would benefit from peer reviews… so say as an example a panel of German officials review a weekend of PL football and give their impartial advice on how they would have dealt with decisions etc and vice versa… English officials do similar in Germany.

Transparency among the reffing organisations, faith that PGMOL aren’t biased/on the take… And surely getting the insights from a different league has to be beneficial in improving how games are officiated
