I cant see why a male teenager from a poor country, who has been dropped by a European football academy and who then, rather than go home, decides they identify as female in order to get signed by a women's team, is a men's football problem.
At the moment rules are not clear and chromosome wise these boys will have the same chromosome profile as some with DSDs, the sort of DSD where something has gone wrong with the external appearance of genitals but where testes exist internally.
Given the recent story of Spanish soldiers and police identifying as female to get better benefits, it would be absolutely logical for young sportsmen to do the same in order to get professional footballing job. Transwomen are allowed in University women's teams and elsewhere and US and European teams are signing men with DSDs.
Rules need to be clarified and adhered to. Otherwise women will lose out.
