Liverpool boss Brendan Rodgers has plans for a summer clearout.
The Sunday Mirror says goalkeeper Pepe Reina, defenders Martin Skrtel and Jose Enrique, and midfielders Jordan Henderson and Stewart Downing are all in danger of the axe.
Liverpool will also let Sebastian Coates leave and look for a buyer for Andy Carroll, who has been on loan at West Ham.
An Anfield source said: "The manager has now imprinted his style of play on the club, but next season will be more important in terms of results.
"There are a lot of talented players at Liverpool, but the club needs people with strong mentalities who can perform under pressure."
