Stewards earn roughly £10 an hour, well that’s what I get at Stevenage FC on match day. Probably more at Premiership games as Stevenage get about 3000 at their games so hugely lower. I’ve been involved in crowd management for over 40 years and my experience is that if fans want to invade the pitch from all sides despite police and stewards being present than they’ll do it. Even having the pitch perimeter covered by security, which financially you couldn’t do and nor would clubs have the workforce to do, it wouldn’t stop the invasion.
