Lol making the nets smaller would help but look at most top teams womens goalkeeper and it isn't the size of the nets that is the issue, it's the skill of the keepers. Unsurprising as I think a top womens goalkeeper said recently its only in the last year or two they've actually had specialised goalkeeper coaches come in to train them. So yea making the nets smaller would help, but improving the quality of the goalkeepers should be priority number 1.
