She is, but she's still relatively inexperienced, she was still an assistant referee as recently as 4 years ago. The point I guess I'm making is that referees in the WSL will have refereed a tiny fraction of games compared to referees in the EPL. Think I'm right in saying that Mel mainly referees in the National League on the male side, so it is taking a referee from step 5 and putting them in front of an almost full house at the Emirates for a televised game, it is a whole different level of pressure.
I'm not saying this is wrong by the way, it wouldn't be a good look having make referees officiating womens top level games. But with the move to play a much bigger percentage of games in the main stadiums, along with more and more being televised, it certainly ups the pressure on the referees and they aren't as acclimatised to it as their male SG1 colleagues are. So for all it is the right thing to be doing, the clubs will have to accept that there will be mistakes whilst the officials get more experienced in that environment. If they can't / won't accept that they will need to approach PGMO and ask that the likes of Oliver, Taylor, Kavanagh, etc, take charge of these games, but that obviously stunts the development of female officials.
