A Liverpool supporters' group has called on fans at Saturday's match at Anfield to walk out in protest at the club's new ticket prices.
Spion Kop 1906 asked supporters to show their unhappiness in the 77th minute of the Barclays Premier League clash with Sunderland.
Liverpool on Tuesday announced a new pricing structure for the 2016-17 season, which will see the most expensive match day ticket cost £77 - up from £59 - in the redeveloped Main Stand.
A message posted by Spion Kop 1906 on Twitter on Thursday said: "Let's make sure the owners know this is unacceptable.
"On 77 minutes, leave your seat and walk out. Tell your mates and your family. Tell the people around you. Tell them why.
"Walk out on 77 minutes and show you care. Love the team - hate the prices. #WalkOutOn77".
Spion Kop 1906's idea has been backed by fellow fans' group Spirit of Shankly, who on Tuesday said it was "extremely disappointed" with the "unfair and unnecessary" prices.
The new pricing structure will also see the cost of the most expensive season ticket price rise to £1,029. The lowest will cost £685.
Liverpool say 64 per cent of prices will freeze or decrease, with 45 per cent of match-day tickets also seeing a reduction.
New initiatives include a new £9 match ticket for local youngsters for the club's three category C games and the introduction of 1,000 young adult tickets for 17 to 21-year-olds.
Tuesday's announcement from the club followed a 13-month consultation process, which the Spirit of Shankly group was involved in.
Liverpool chief executive Ian Ayre has defended the price changes, saying: ''We always carefully consider ticket pricing to ensure the long-term sustainability and competitiveness of the club while listening to the views of our match-going fans to understand the priorities around accessibility and affordability.
''The redevelopment of our Main Stand and increased capacity has given us flexibility to freeze or reduce more than half of all tickets across the stadium which is reflected in our longer-term plan to give fans more choice on what price they pay to attend a game.
''We recognise the incredible importance of ticket pricing to our match-going fans and we take the responsibility very seriously in determining pricing at Anfield.''
The redeveloped Main Stand will accommodate 8,500 new seats, half of which will be allocated to corporate hospitality.
