Speaking on the Today programme, Hayes said: "I think you need to get more owners in to ask them that question, because they're the people you have to ask that question to. I'm not the one in charge of that."
When asked if club owners are "ready for that", Hayes replied: "Yeah, of course, they're not, otherwise it would have happened by now. I've said this a million times over – you can find a female pilot, a female doctor, a female lawyer, a female banker, but you can't find a female coach working in the men's game, leading men. It just shows you how much work there is to be done."
