I would have suggested that they don't even try to introduce something new other than the one we've been used to already, there may be different discrepancies in their order of making decisions to judge towards the use of the blue card over the yellow or red card, but if there's going to be a full engagement on how to adopt and use this new approach over each countries, and that they are ready to take the responsibility of orientating the football sections of each countries, make a guidelines that could support the adoption and do a follow-up, this may not bring about diversification in judging for an either blue, red or yellow card.
So for that, I may not support the idea of not entertaining new developments and additions to the already football features that we have, and for sure this new rule will make football more better than we think so let us remain positive, about this whole thing and look forward to seeing a better side in football when it fully implemented in International football.
