Answer:
Assuming a male and female athlete receives equal prize money, generally speaking, the top male athletes earn more due to better sponsorship and endorsement deals. Research conducted by a United Kingdom's organisation shows that sponsors are more attracted by male athletes as male athletes tend to be more marketable, Most popular teams are very old and way before female rights were considered so male football was the only option, In general Most male footballers are Easily more recognisable and perform better than most female footballers, Games like fifa featured Only male sport and only in their second newest game, they had actually featured a female league, These more famed footballers get more sponsors and deals and play this game, so it became more popular, its hard to even recognise even the best of the best female footballers, so i think they deserve to be payed more than females
hope this helped!!
