If we overachieved, it's by what, 1 game? At home surely quarter finals was considered the bare minimum for a pass. In a tournament where powerhouses like the USA and Germany were probably at the worst they've been for decades, it wasn't that farfetched we should make the semi. We did get lucky relying on other results to win the group in the end and we could have faced England much earlier.
Women's football has moved forward rapidly since the World Cup though, we do seem to be getting left behind. The current coaching situation clearly isn't helping.
In Asia though it's still a pretty terrible standard outside of Japan, playing at home, that really should be our only competetive match for the tournament, so we really need to be winning it. I don't see us changing much until that tournament, after that though, we need a massive rebuild.
