I couldn't lip read, but it has triggered me thinking that (and whilst women don't want to be treated differently from men I do think that the women's game is generally less physical) women's football could advance from 2 cards.
A yellow card - you've been warned that you're 1 card away from spending time on the naughty step.
An orange card - results in 10 minutes on the naughty step, either because it's a 2nd yellow or it's "worse" than yellow but not red.
A red card - dismissal, either because it's a 3rd yellow or 2nd orange or (obviously) serious foul play.
Most women players would, I think, want to play 11 v 11 unless something is warranted.
Perhaps the difficult aspect of this is DOGSO - personally I'd prefer orange to red unless there's serious foul play - for other sports (such as rugby & hockey) the advantage of having 10 minutes against reduced opposition does usually result in a benefit to the non-offending team.
Whilst the crowds are away (or significantly reduced) there are so many potential low-lying fruit which once harvested would really improve football for all concerned. And there's no real reason why a stand-alone competition couldn't trial law changes at any stage of the season. If VAR can be brought in at the latter rounds for instance ...... so can other law changes, or are my spectacles too tinted?
