In italy, we have a annual book, curated by Panini, with weight and height of alls players from serie A and serie B. I myself followed the weight task of Italian footballers.
This move is simply to open the field for women's football. They hope that 5% of national team managers will become manager of football female. The weight is a protection for women's football. For me it's unwatchable football, I even tried the Olympic final, unwatchable.
I hope they can retrace their steps at least for the weight.
