Premier League football clubs sponsored by betting firms have been accused of luring children into gambling. Ten top-tier clubs feature a gambling firm as either their main shirt sponsor or sleeve sponsor. Clubs are also using youth players – some as young as 15 – to promote gambling websites, in breach of advertising regulations. The gambling operators deny deliberately targeting children, but some of the websites advertised host free casino-style slots games. Critics say these are the “number one risk factor” in developing a gambling problem in later life. Football Association rules ban under-18 players from promoting gambling, but Newcastle United’s entire under-18s squad was pictured on the club’s website wearing strips with the Fun88 logo.
