It's a tricky one. Firstly it's not up to individual businesses to make sure that their employees earn enough, it's up to the government to ensure that people have enough income to sustain a reasonable life. Also I would assume that a football club would have a lot of part time staff who may only work on matchdays. A student or retiree or normal joe down the road might like getting his few pound for working a few hours on matchday eventhough he is technically on minimum wage. It's not as simple as just pay the living wage and we're great. It's more an issue for government than for industry IMO, however everyone knows the government won't sort things like economic traps out ever.
