Liverpool fans protest about prices during Premier League game with Hull
Banners displayed in the Kop read "supporters not customers" and "Kop kids pay adult prices".
In a message on their website, fans' group Spirit of Shankly said: "Ticket prices continue to rise, outstripping inflation by over 1,000% in the last 20 years.
"It is why we, and others including the Spion Kop 1906 group, have continually campaigned on ticket prices, calling for them to be lowered and made more affordable to make Anfield more accessible for current and future generations."
According to the recent BBC's Price of Football survey, the cheapest price for a ticket at a Liverpool home game is £37, more than the Premier League average of £28.80.
Only Chelsea, at £50, charge more for their cheapest ticket.
