All of the above know what it's like to have played on both sides of Stanley Park. Its a phenomenon rarely encountered in the modern men's game, with the widening chasm in the fortunes Liverpool and Everton on the pitch seemingly correlating with the acute hostilities off it.
In the women's game, crossing that city divide is a little more common; something which can perhaps be attributed to the fact there are just 12 clubs for players to move between in the Women's Super League. However, while the rivalry between Liverpool and Everton Women may not be as acrimonious or deep-rooted as the one fostered by their male counterparts, the desire to come out on top in the Merseyside derby is no less great.
