No shows basically. There were gaps even in areas that I know were completely sold out. I've been in a similar size United women's crowd at Leigh before - City in the Cup a couple of years ago. But this was easily the biggest crowd we've seen at Leigh since before the Covid shutdown.
Part of the issue for new fans will have been transport and parking. There were people arriving 20 minutes or more late, presumably because they ended up struck in traffic jams or had to go looking for car parks away from the ground.
The complication with Leigh is that the stadium normally has a predominantly local crowd for Leigh Rugby League matches. It's not really set up for people arriving from all across Manchester. Plus crowds like today are generally not match hardened crowds! Lots of kids and family units of parents, grandparents and little ones - they give in easier than regular matchgoers
Incidentally actual capacity at LSV is around 8k for us because we don't use the standing area.
