A Liverpool supporters group is planning a mass walkout during Sunderland's game against Liverpool at Anfield on Saturday in protest at rising ticket prices.
Fans group Spion Kop 1906 have taken to social media to urge home fans to leave the stadium on 77 minutes after it was revealed the most expensive seats in the redeveloped Main Stand will cost £77 next season, report the Liverpool Echo.
Sam Allardyce takes his struggling Sunderland side to Anfield for the Premier League clash fresh from the 1-0 home defeat to Manchester City.
But the famous old ground may not be as full come the full-time whistle, if the supporters groups get their way.
The protest has the backing of supporters' union Spirit of Shankly, who along with representatives from Spion Kop 1906 were involved in discussions with the club over prices, while Liverpool's own supporters committee branded the newly reviewed ticket prices “morally unjustifiable”.
Anfield is currently undergoing a major multi-million pound revamp and next season the most expensive season ticket price will be £1,029 with the lowest costing £685, report the Echo.
The highest Main Stand ticket will go up from £59 to £77.
Spion Kop 1906 tweeted: "Saturday is your chance to make your feelings known. Unhappy with the prices for next season? Then #WalkOutOn77
"77 - a number associated with @LFC. From Rome '77 to £77 a ticket. Let's give the number 77 a meaning on Saturday. #walkouton77
"If the club want to charge up to £77 a ticket, make your feelings known and walk out on 77 minutes."
Liverpool insist 64 per cent of season ticket prices will be reduced or frozen.
But a spokesman for Spirit of Shankly said: "There are some small reductions but the news overall is that prices are going up by quite large amounts.
"This is despite the fact that the club promised to work with supporters’ groups and take their views on board.
"In dealings we have had with the club the people at Anfield have always been reasonable and approachable, our frustration at these unnecessary price hikes is entirely with the owners.
"We believe the decision-making here has come from Boston (where Fenway Sports Group is based)."
Liverpool chief executive Ian Ayre said: "What is affordable to one person is different to another.
"With that in mind we tried to create a range of prices.
"We have listened to fans’ concerns and come up with some new initiatives, and we hope there is something for all."
